 # LeoCRM Security & Data Risk Assessment
 **Date:** 2026-07-26
 **Assessor:** Security Data Engineer (A0 Orchestrator)
 **Project:** LeoCRM at `/a0/usr/workdir/leocrm-fix`
 ---
 ## Summary
 | Severity | Count |
 |----------|-------|
 | CRITICAL | 5     |
 | HIGH     | 8     |
 | MEDIUM   | 8     |
 | LOW      | 5     |
 | **Total**| **26**|

 ## CRITICAL Issues
 ### C-1: Redis Default Password `changeme` in docker-compose.yml
 **File:** `docker-compose.yml:53`
 **Risk:** Redis stores session data, CSRF tokens, and rate-limit counters. The default password `changeme` is trivially guessable. If Redis port 6379 is exposed, an attacker can read/modify all sessions, steal CSRF tokens, and bypass rate limits.
 **Remediation:** Remove the default fallback. Require `REDIS_PASSWORD` as a mandatory variable (`${REDIS_PASSWORD:?REDIS_PASSWORD is required}`). Use a strong randomly generated password in production.
 ### C-2: No SECRET_KEY in `.env` — Insecure Default Active in Development
 **File:** `.env` (missing `SECRET_KEY`), `app/config.py:55`
 **Risk:** `.env` has no `SECRET_KEY`. The config defaults to `"change-me-in-production-use-a-secure-random-string"`. While `get_settings()` raises in production mode, `.env` sets `ENVIRONMENT=development`, so the default key is silently used. Any signing/token operation using `secret_key` is compromised.
 **Remediation:** Add a strong random `SECRET_KEY` (min 32 chars) to `.env`. Fail-fast in all environments if the default key is detected, not just production.
 ### C-3: PostgreSQL and Redis Ports Exposed to Host
 **File:** `docker-compose.yml:37-38, 56-57`
 **Risk:** `ports: "5432:5432"` and `ports: "6379:6379"` expose the database and Redis to the host network. Combined with weak/default credentials, this allows direct external access to all session data and the entire database.
 **Remediation:** Remove port mappings for production. Use Docker internal networking only (`crm-net`). If debug access is needed, bind to `127.0.0.1:5432:5432` and document it as dev-only.
 ### C-4: Unauthenticated Error Endpoint Forwards Data to External Forgejo
 **File:** `app/routes/errors.py:54-90`, `app/plugins/builtins/forgejo_error_reporter/service.py:151-250`
 **Risk:** The `/api/v1/errors` endpoint requires no authentication. CSRF middleware explicitly bypasses token checks for this path (line 48 of `middleware.py`). Any unauthenticated attacker can POST arbitrary error data (message, stack, URL, userAgent, and **arbitrary context dict**) which gets forwarded to an external Forgejo instance as a public issue. The `context` field accepts `dict[str, Any]` with no size limit on individual keys — an attacker can exfiltrate data or inject malicious content into Forgejo issues.
 **Remediation:** Require authentication for error reporting. If unauthenticated errors are needed, strip the `context` field entirely, add strict schema validation with size limits on all fields, and add a CAPTCHA or stricter rate limiting.
 ### C-5: Plaintext Database Password in `.env`
 **File:** `.env:1`
 **Risk:** `DATABASE_URL=postgresql+asyncpg://leocrm:leocrm@localhost:5432/leocrm` embeds the DB password `leocrm` in plaintext. While `.gitignore` covers `.env`, the password is weak and identical to the username. If the file is accessed via any path traversal, backup leak, or container escape, the database is fully compromised.
 **Remediation:** Use a strong unique password. Separate `DATABASE_URL` construction from credential storage where possible (e.g., use individual `POSTGRES_USER`, `POSTGRES_PASSWORD`, `POSTGRES_HOST`, `POSTGRES_DB` env vars and construct the URL in code).
 ---
 ## HIGH Issues
 ### H-1: Rate Limiter Trusts X-Forwarded-For Without Validation
 **File:** `app/core/rate_limit.py:43-45`
 **Risk:** `get_client_ip()` blindly trusts the `X-Forwarded-For` header. An attacker can set arbitrary values to bypass rate limits on login, password reset, and other endpoints. Each request with a different spoofed IP creates a new rate-limit counter.
 **Remediation:** Only trust `X-Forwarded-For` from known proxy IPs. Configure a trusted proxy list and validate the header chain. Use Starlette's `ProxyHeadersMiddleware` or validate against a `TRUSTED_PROXIES` env var.
 ### H-2: Duplicate `get_redis()` Functions — Connection Leak
 **File:** `app/core/auth.py:53-66` and `app/core/auth.py:94-96`
 **Risk:** Two `get_redis()` functions exist. The first (line 53) returns a singleton. The second (line 94) creates a **new Redis connection on every call**. Code importing `get_redis` may use either version. The middleware (line 69) creates its own Redis connection per request. This leads to connection pool exhaustion under load.
 **Remediation:** Remove the second `get_redis()` (line 94-96). Ensure all code uses the singleton version. The middleware should use `get_redis()` from `app.core.auth` instead of creating its own connection.
 ### H-3: CSRF Middleware Creates New Redis Connection Per Request
 **File:** `app/core/middleware.py:69-90`
 **Risk:** For every unsafe HTTP request, the middleware creates a new `aioredis.from_url()` connection, uses it, then closes it. Under load, this creates thousands of connections and can exhaust Redis connection limits.
 **Remediation:** Use the global Redis singleton via `from app.core.auth import get_redis`. Remove the per-request connection creation and the `finally: await redis.close()` block.
 ### H-4: CSRF Token Stored Plaintext in PostgreSQL
 **File:** `app/core/auth.py:141` (`SessionModel` stores `csrf_token`)
 **Risk:** The CSRF token is stored as plaintext in the PostgreSQL `sessions` table (audit trail). If the database is compromised, all active CSRF tokens are available for CSRF attacks.
 **Remediation:** Store only a hash of the CSRF token in PostgreSQL (like `hash_token()` already exists for session tokens). Compare hashes during validation.
 ### H-5: No File Upload Validation in Storage Backend
 **File:** `app/core/storage.py:69-128`
 **Risk:** `LocalStorage` performs no validation on uploaded files:
 - No path traversal protection: `os.path.join(self.base_path, path)` with a malicious `path` containing `../../` can write anywhere on the filesystem
 - No file type/extension whitelist
 - No file size limit
 - No content-type validation
 - `get_url()` returns the full filesystem path, leaking internal directory structure
 **Remediation:** Sanitize `path` with `os.path.realpath()` and verify it's within `base_path`. Enforce file size limits, extension whitelist, and MIME type validation. Return relative paths from `get_url()`, not absolute filesystem paths.
 ### H-6: WebSocket Connections Lack Authentication Verification
 **File:** `app/plugins/builtins/kommunikation/websocket_manager.py:23-28`, `app/plugins/builtins/ai_ui_control/websocket_manager.py:40-46`
 **Risk:** Both WebSocket managers accept connections via `connect(websocket, user_id)` without verifying that `user_id` is authenticated. The security depends entirely on the calling route. If any WebSocket route passes an untrusted `user_id` (e.g., from query params), an attacker can impersonate any user. There is also no origin verification on WebSocket connections.
 **Remediation:** Verify session cookie inside `connect()` before `websocket.accept()`. Validate the `Origin` header against allowed CORS origins. Add authentication middleware for WebSocket routes.
 ### H-7: In-Memory Rate Limiter in Error Endpoint — Fails with Multiple Workers
 **File:** `app/routes/errors.py:21-40`
 **Risk:** The error endpoint uses a process-local `defaultdict(deque)` for rate limiting. With multiple Uvicorn workers (common in production), each worker has its own counter. An attacker can make `RATE_LIMIT * num_workers` requests per minute.
 **Remediation:** Use the Redis-based `check_rate_limit()` from `app/core/rate_limit.py` instead of the in-memory implementation.
 ### H-8: No CSRF Protection on WebSocket Connections
 **File:** Both WebSocket managers
 **Risk:** WebSocket connections are not protected against CSRF. A malicious site can open a WebSocket to the CRM backend via JavaScript `new WebSocket()` and send commands as the authenticated user (cookies are sent automatically with SameSite=Strict for same-site, but cross-site WebSocket hijacking is still possible if SameSite is configured differently or cookies are sent via `credentials`).
 **Remediation:** Verify the `Origin` header on WebSocket upgrade requests. Reject connections from untrusted origins.
 ---
 ## MEDIUM Issues
 ### M-1: Login Response Leaks `is_system_admin` Flag
 **File:** `app/routes/auth.py:78`
 **Risk:** The login response includes `"is_system_admin": user.is_system_admin`. An attacker who compromises a session or intercepts the response knows whether the account has system-wide privileges, enabling targeted attacks.
 **Remediation:** Do not include `is_system_admin` in the login response. The frontend can determine admin status via the `/me/permissions` endpoint.
 ### M-2: Weak Password Validation — No Complexity Requirements
 **File:** `app/schemas/auth.py:10` (login: `min_length=1`), `app/schemas/user.py:11` (create: `min_length=8`)
 **Risk:** Login accepts any password length (min_length=1). User creation requires min 8 chars but no complexity (uppercase, lowercase, digits, special chars). Users can set passwords like `aaaaaaaa`.
 **Remediation:** Add password complexity validation (min 12 chars, mixed case, digits, special chars) for user creation and password reset. Keep login min_length=1 to avoid leaking whether the password was partially correct.
 ### M-3: F-String Interpolation of Table/Column Names in Raw SQL
 **File:** `app/plugins/builtins/unified_search/embedding.py:194`, `search_engine.py:153`, `routes.py:294,300`, `jobs.py:183,228`
 **Risk:** Multiple raw SQL queries use f-strings to interpolate table and column names: `f"UPDATE {table} SET ..."`, `f"SELECT {emb_col} FROM {table_name} ..."`. While the values come from hardcoded `table_map` dicts (not user input), this pattern is fragile — a future change could introduce user-controlled values into the map.
 **Remediation:** Use SQLAlchemy ORM queries instead of raw SQL where possible. If raw SQL is needed, validate table/column names against an allowlist before interpolation, or use `sqlalchemy.sql.quoted_name` for safe identifier quoting.
 ### M-4: Forgejo Error Reporter Sends Full Context to External Service
 **File:** `app/plugins/builtins/forgejo_error_reporter/service.py:196-199`
 **Risk:** The error reporter serializes the entire `context` dict into the Forgejo issue body as JSON. If frontend error reporting includes sensitive data (user tokens, PII, tenant data), it will be written to an external Forgejo repository as a public issue.
 **Remediation:** Add a field-level allowlist for context data. Strip or redact sensitive keys (tokens, passwords, emails, phone numbers). Consider making Forgejo issues private/confidential.
 ### M-5: Config Has Hardcoded Default Secret Key
 **File:** `app/config.py:55`
 **Risk:** The default `secret_key = "change-me-in-production-use-a-secure-random-string"` is a known public value. While production mode checks for it, development mode silently uses it. If dev environments are exposed (even temporarily), all signed tokens are forgeable.
 **Remediation:** Remove the default value entirely. Make `secret_key` a required field with no default. Fail in all environments if not set.
 ### M-6: `LocalStorage.get_url()` Returns Absolute Filesystem Path
 **File:** `app/core/storage.py:116-117`
 **Risk:** `get_url()` returns `self._full_path(path)` which is the absolute filesystem path (e.g., `/data/uploads/tenant1/file.pdf`). If this URL is returned to the frontend or used in API responses, it leaks the internal directory structure and can aid path traversal attacks.
 **Remediation:** Return a relative path or a signed download URL that routes through an authenticated API endpoint.
 ### M-7: Inconsistent Environment Configuration in `.env`
 **File:** `.env:3,4`
 **Risk:** `.env` sets `ENVIRONMENT=development` but `SESSION_COOKIE_SECURE=true`. In development with HTTP, secure cookies won't be sent, causing auth failures. More importantly, the `ENVIRONMENT=development` setting disables the production safety checks in `get_settings()`, allowing the default `SECRET_KEY` to be used.
 **Remediation:** Use separate `.env.development` and `.env.production` files. Ensure development configs are never accidentally deployed.
 ### M-8: Permission Cache Falls Back to Stale Data on DB Error
 **File:** `app/core/permissions.py:337-344`
 **Risk:** When `_get_current_permission_version()` fails (DB error), the code sets `current_version = cached_version` and uses potentially stale cached permissions. If a user's permissions were revoked during the DB outage, they retain elevated access.
 **Remediation:** On DB error, either fail closed (deny access) or use a shorter stale-while-error TTL. Log the event as a security incident.
 ---
 ## LOW Issues
 ### L-1: `document.write()` with DOM Clone in Print Utility
 **File:** `frontend/src/utils/print.ts:54, 127`
 **Risk:** `printElement()` and `exportToPDF()` use `document.write()` with `clone.outerHTML`. If the printed DOM element contains user-controlled content (e.g., contact notes with HTML), it executes in a new window context. The new window is same-origin, limiting the impact, but it's still an unnecessary risk.
 **Remediation:** Use DOM APIs (`appendChild`, `importNode`) instead of `document.write()`. Alternatively, sanitize the cloned HTML before writing.
 ### L-2: Session Data Stored in Redis Without Encryption
 **File:** `app/core/auth.py:130-134`
 **Risk:** Session data (user_id, tenant_id, email, role, csrf_token, is_system_admin) is stored as plaintext JSON in Redis. Anyone with Redis access can read all active sessions.
 **Remediation:** Encrypt session data before storing in Redis, or accept the risk given Redis should be network-isolated. At minimum, ensure Redis requires authentication and is not exposed.
 ### L-3: No Security Headers Middleware
 **File:** No security headers middleware found
 **Risk:** The application does not set security headers like `X-Content-Type-Options`, `X-Frame-Options`, `Strict-Transport-Security`, `Content-Security-Policy`.
 **Remediation:** Add a security headers middleware or use `starlette-securehead`/`secure` package.
 ### L-4: No Origin Verification on WebSocket Upgrade
 **File:** Both WebSocket managers
 **Risk:** Neither WebSocket manager checks the `Origin` header before accepting connections. While cookies with `SameSite=Strict` provide some protection, some browsers and non-browser clients may not respect SameSite on WebSocket connections.
 **Remediation:** Check `websocket.headers.get("origin")` against `settings.cors_origin_list` before calling `websocket.accept()`.
 ### L-5: Unbounded Feedback/Command Storage in AI UI Control WebSocket
 **File:** `app/plugins/builtins/ai_ui_control/websocket_manager.py:94-103`
 **Risk:** `store_feedback()` stores feedback dicts without size limits. `cleanup_stale()` only runs when explicitly called. An attacker who can send WebSocket messages could fill memory with large feedback payloads.
 **Remediation:** Add size limits on feedback payloads. Run `cleanup_stale()` on a timer or on each `connect()`/`disconnect()`.
 ---
 ## Positive Findings
 1. **Dockerfile security:** Multi-stage build, non-root user (`appuser` UID 1000), healthcheck configured, no secrets baked into image.
 2. **RLS implementation:** PostgreSQL Row Level Security with `FORCE` (migration 0028) ensures tenant isolation even for table owners. `set_tenant_context()` uses parameterized queries.
 3. **Password hashing:** bcrypt with configurable rounds (default 12).
 4. **Session tokens:** `secrets.token_urlsafe(32)` — cryptographically secure.
 5. **XSS protection:** `HtmlBlock.tsx` and `SignatureManager.tsx` use `DOMPurify.sanitize()` before `dangerouslySetInnerHTML`.
 6. **RBAC architecture:** Deny-list takes precedence over allow-list. Field-level permissions with strictest-wins merging. Permission version-based cache invalidation.
 7. **No user enumeration:** Password reset endpoint always returns 200.
 8. **SQL injection:** ORM queries use parameterized statements throughout. Raw SQL in `unified_search` uses hardcoded maps (not directly exploitable).
 9. **`.gitignore`** properly covers `.env`, `.env.*`, and excludes example files.
 10. **Production safety checks** in `get_settings()` validate `SECRET_KEY`, `SESSION_COOKIE_SECURE`, and `STORAGE_PATH`.
 ---
 ## Migration & Data Loss Risks
 1. **RLS policies:** Multiple migrations (0001, 0002, 0004, 0015, 0021, 0028) create and modify RLS policies. Migration 0028 adds `FORCE ROW LEVEL SECURITY`. Ensure all migrations are applied in order before production deployment.
 2. **Backup risk:** No backup/restore procedure found in the repository. The `last_backup_at` system setting is referenced in automation jobs but no backup script exists.
 3. **Volume persistence:** `docker-compose.yml` defines named volumes for `pgdata`, `redisdata`, and `storage`. Good for persistence, but no backup strategy documented.
 4. **Migration rollback:** Down migrations exist but should be tested. RLS policy down migrations disable RLS — running a rollback in production would expose all tenant data.
 ---
 ## Remediation Priority
 1. **Immediate (before any production deploy):** C-1, C-2, C-3, C-4, C-5, H-1, H-2, H-3
 2. **Short-term (within 1 sprint):** H-4, H-5, H-6, H-7, H-8, M-1, M-2, M-5
 3. **Medium-term (within 2 sprints):** M-3, M-4, M-6, M-7, M-8, L-1, L-2, L-3, L-4, L-5

 - **Datei:** `app/core/auth.py` Zeilen 53 + 94
 - **Problem:** Zweite Definition überschreibt Singleton, erzeugt pro Aufruf neue Verbindung → Connection Leak
 - **Fix:** Zweite `def get_redis()` (Zeile 94) löschen. Erste Definition (Zeile 53) beibehalten.
 - **Aufwand:** 5 Min
 - **Risiko:** Keines — erste Definition ist korrekt
 ### B2. Plugin-Routen-Registrierung reparieren
 - **Datei:** `app/main.py` Zeilen 375-416
 - **Problem:** Alle Plugin-Routen werden statisch in `create_app()` registriert, unabhängig vom Aktivierungsstatus. Deaktivierte Plugins bleiben erreichbar. Kommentar in Zeile 416 sagt das Gegenteil.
 - **Fix:**
  1. Statische Registrierung aus `create_app()` entfernen
  2. In `lifespan()` nur Routen für `active=True` Plugins registrieren
  3. `Depends(require_active_plugin("name"))` als zentrale Prüfung ergänzen
  4. Bei Deaktivierung: Router entfernen oder 403-Dependency ergänzen
 - **Aufwand:** 2-3 Std
 - **Risiko:** Mittel — muss sicherstellen dass keine Route doppelt registriert wird
 ### B3. UploadFile Route-Registration Bug
 - **Dateien:** `app/plugins/builtins/dms/routes.py`, `calendar/routes.py`, `mail/routes.py`, `kommunikation/routes.py`, `ai_assistant/routes.py`
 - **Problem:** FastAPI kann `UploadFile` nicht als Response-Model auflösen → 5 Plugins failen beim Registrieren mit `Invalid args for response field`
 - **Fix:** `response_model=None` zu allen Endpoints mit `UploadFile`-Rückgabe hinzufügen, oder Return-Type auf `Response`/`dict` ändern
 - **Aufwand:** 30 Min
 - **Risiko:** Keines — Routen sind aktuell gar nicht registriert
 ### B4. DMS-Upload auf echtes Streaming umstellen
 - **Datei:** `app/plugins/builtins/dms/routes.py` Zeilen 444-472
 - **Problem:** Chunks werden in `list[bytes]` gesammelt, dann `b"".join()` → 100MB Datei = 200MB+ RAM. `save_stream()` existiert aber wird nicht benutzt.
 - **Fix:**
  ```python
  async def chunk_generator():
      while chunk := await file.read(CHUNK_SIZE):
          yield chunk
  await storage.save_stream(storage_path, chunk_generator())
  ```
  Hash und Größe während des Streams berechnen.
 - **Aufwand:** 1 Std
 - **Risiko:** Gering — save_stream() ist bereits implementiert
 ### B5. Outbox-Worker: Event-Handler registrieren
 - **Datei:** `app/core/worker.py` `on_startup()`
 - **Problem:** Worker liest Events aus Outbox, published an lokalen EventBus, aber es sind keine Handler registriert → Events werden als `published` markiert ohne Verarbeitung
 - **Fix:**
  1. In `on_startup()`: Plugin-Event-Handler registrieren (wie in `lifespan()` der API)
  2. `webhook_dispatcher._dispatch_event` an EventBus subscriben
  3. Plugin-Participant-Handler registrieren
 - **Aufwand:** 2 Std
 - **Risiko:** Mittel — muss gleiche Handler wie API-Container registrieren
 ### B6. Passwort-Reset-Mailjob implementieren
 - **Dateien:** `app/services/auth_service.py`, `app/core/jobs.py`, `app/core/job_registry.py`
 - **Problem:** `send_password_reset_email` Job wird gequeued aber nie registriert → Mail wird nicht versendet. Token wird in Logs geschrieben (Zeile 240-241).
 - **Fix:**
  1. `send_password_reset_email` Worker-Funktion implementieren (SMTP/IMAP)
  2. Mit `register_job()` registrieren
  3. `logger.warning("raw_token for development: %s", raw_token)` entfernen
  4. Token nur im Development-Mode loggen, nie in Production
 - **Aufwand:** 2 Std
 - **Risiko:** Gering
 ### B7. Webhook SSRF-Schutz + Secret-Behandlung
 - **Dateien:** `app/services/webhook_service.py`, `app/schemas/webhook.py`
 - **Problem:** Kein SSRF-Schutz — User können interne Dienste ansprechen (redis:6379, postgres:5432, 169.254.169.254). Webhook-Secret wird im Response zurückgegeben.
 - **Fix:**
  1. SSRF-Prüfung: DNS auflösen, private IPs blocken (10.x, 172.16-31.x, 192.168.x, 127.x, 169.254.x, ::1)
  2. Redirects deaktivieren oder prüfen
  3. Protokoll-Allowlist (nur https)
  4. `secret` aus `WebhookResponse` entfernen
  5. Secret gehasht in DB speichern
 - **Aufwand:** 3 Std
 - **Risiko:** Gering
 ### B8. RLS: Separater DB-Runtime-User
 - **Dateien:** `docker-compose.yml`, `alembic/versions/0044_db_roles.py` (neu)
 - **Problem:** `POSTGRES_USER` (crm_user) ist Superuser → umgeht RLS auch mit FORCE. Spätere Tabellen (user_preferences, saved_filters, etc.) haben keine RLS-Policy.
 - **Fix:**
  1. Neue Migration `0044_db_roles.py`: erstellt `crm_runtime` (NOSUPERUSER, NOBYPASSRLS)
  2. `crm_runtime` bekommt nur SELECT/INSERT/UPDATE/DELETE Rechte
  3. `docker-compose.yml`: API und Worker nutzen `crm_runtime`, Migrationen nutzen `crm_owner`
  4. Neue Migration `0045_rls_new_tables.py`: RLS für alle Tabellen mit `tenant_id` die nach 0028 hinzukamen
 - **Aufwand:** 4 Std
 - **Risiko:** Hoch — muss bestehende Datenbanken migrieren ohne Datenverlust
 ### B9. .env.docker.example korrigieren
 - **Datei:** `.env.docker.example`
 - **Problem:** Verwendet `AUTH_SECRET` statt `SECRET_KEY` (config.py erwartet `SECRET_KEY`)
 - **Fix:** `AUTH_SECRET` → `SECRET_KEY` umbenennen
 - **Aufwand:** 5 Min
 - **Risiko:** Keines
 ### B10. Redis-Default-Passwort + exponierte Ports
 - **Datei:** `docker-compose.yml`
 - **Problem:** Redis-Passwort default `changeme`, PostgreSQL (5432) und Redis (6379) Ports exponiert
 - **Fix:**
  1. Redis-Passwort als Required-Env ohne Default
  2. `ports:` Sektion für DB und Redis entfernen (nur internes Docker-Netzwerk)
  3. Falls Debug-Zugriff nötig: nur an 127.0.0.1 binden
 - **Aufwand:** 15 Min
 - **Risiko:** Gering — bestehende Setups müssen .env anpassen
 ---
 ## Phase 2: Hohe Priorität (kurz nach Release)
 ### H1. Unauthentifizierter Error-Endpoint absichern
 - **Datei:** `app/routes/errors.py`
 - **Problem:** `POST /api/v1/errors` ohne Auth, sendet Daten an Forgejo als öffentliches Issue. Context-Dict kann sensible Daten enthalten.
 - **Fix:**
  1. Context-Felder filtern (keine Tokens, Passwörter, Headers)
  2. Forgejo-Issues nur in non-production erstellen
  3. Rate-Limit auf IP-Basis (bereits vorhanden, aber in-memory → bei Multi-Worker unzuverlässig)
  4. Optional: Auth erforderlich, aber dann funktioniert Frontend-Error-Logging nicht mehr → besser: nur sanitisierte Daten akzeptieren
 - **Aufwand:** 1 Std
 ### H2. Rate-Limiter IP-Spoofing
 - **Datei:** `app/core/rate_limit.py` Zeile 43
 - **Problem:** Vertraut `X-Forwarded-For` blind → IP-Spoofing umgeht Rate-Limits
 - **Fix:** Nur erste IP in X-Forwarded-For verwenden, oder `X-Real-IP` mit Proxy-Validation
 - **Aufwand:** 30 Min
 ### H3. CSRF-Middleware Redis-Verbindung
 - **Datei:** `app/core/middleware.py` Zeile 69
 - **Problem:** Erstellt pro unsafe Request neue Redis-Verbindung → Connection Leak
 - **Fix:** `get_redis()` Singleton verwenden (funktioniert nach B1)
 - **Aufwand:** 10 Min
 ### H4. WebSocket Auth + Origin-Verifikation
 - **Dateien:** `app/plugins/builtins/kommunikation/websocket_manager.py`, `ai_ui_control/websocket_manager.py`
 - **Problem:** `user_id` wird ohne Auth-Verifikation akzeptiert. Keine Origin-Prüfung bei WS-Upgrade.
 - **Fix:**
  1. Session-Token aus Query-Param oder Header validieren
  2. Origin-Header gegen erlaubte Domains prüfen
  3. User-ID aus Session ableiten, nicht aus Client-Param
 - **Aufwand:** 2 Std
 ### H5. File-Upload-Sicherheit
 - **Datei:** `app/core/storage.py`
 - **Problem:** Keine Path-Traversal-Prüfung, keine Type/Size-Limits, `get_url()` leakt Filesystem-Pfade
 - **Fix:**
  1. Filename sanitizen (keine `../`, keine absoluten Pfade)
  2. MIME-Type-Allowlist
  3. Max-File-Size konfigurierbar
  4. `get_url()` gibt relative URL zurück, nicht Filesystem-Pfad
 - **Aufwand:** 1 Std
 ### H6. Security-Headers
 - **Datei:** `app/core/middleware.py` (neu)
 - **Problem:** Keine Security-Headers (HSTS, X-Content-Type-Options, X-Frame-Options, CSP)
 - **Fix:** Middleware ergänzen die diese Headers setzt
 - **Aufwand:** 30 Min
 ### H7. Migration-Repair für bestehende Installationen
 - **Datei:** `alembic/versions/0044_repair_contact_migration.py` (neu)
 - **Problem:** Migrationen 0021 und 0027 wurden nachträglich geändert. Alembic führt sie nicht erneut aus.
 - **Fix:**
  1. Neue Migration die `*_old` Tabellen erkennt und Daten nachmigriert
  2. Integritätsprüfung (Anzahl vergleichen)
  3. Bei Abweichungen hart abbrechen mit Fehlermeldung
 - **Aufwand:** 3 Std
 ---
 ## Phase 3: Mittlere Priorität
 ### M1. Passwort-Komplexität
 - **Datei:** `app/schemas/auth.py`, `app/schemas/user.py`
 - **Problem:** Min-Length 8 bei Erstellung, Min-Length 1 bei Login. Keine Komplexitäts-Requirements.
 - **Fix:** Passwort-Validator ergänzen (min 8 Zeichen, 1 Groß, 1 Klein, 1 Zahl)
 - **Aufwand:** 30 Min
 ### M2. Login-Response: is_system_admin
 - **Datei:** `app/routes/auth.py` Zeile 78
 - **Problem:** `is_system_admin` Flag in Login-Response leakt interne Rolle
 - **Fix:** Flag aus Response entfernen oder nur für Admin-User anzeigen
 - **Aufwand:** 15 Min
 ### M3. Permission-Cache: Stale Data bei DB-Error
 - **Datei:** `app/core/permissions.py` Zeile 337
 - **Problem:** Bei DB-Error fällt Cache auf stale Daten zurück → widerrufene Rechte bleiben aktiv
 - **Fix:** Bei DB-Error: Cache invalidieren und 503 zurückgeben statt stale Daten zu nutzen
 - **Aufwand:** 30 Min
 ### M4. ENVIRONMENT=development vs SESSION_COOKIE_SECURE=true
 - **Datei:** `.env` Zeilen 3-4
 - **Problem:** Inkonsistent — development deaktiviert Prod-Safety-Checks, aber Cookie ist secure
 - **Fix:** In .env.docker.example klar dokumentieren: production → `ENVIRONMENT=production` + `SESSION_COOKIE_SECURE=true`
 - **Aufwand:** 10 Min
 ### M5. Frontend: Unresolved Items
 - **Dateien:** `WelcomeDialog.tsx`, `SavedFilterBar.tsx`, `EntityHistoryPanel.tsx`, `TagBadge.tsx`, `TagSelector.tsx`
 - **Problem:** WelcomeDialog hat `open={false}`. SavedFilterBar/EntityHistoryPanel/TagBadge/TagSelector sind gebaut aber nicht in Seiten integriert.
 - **Fix:**
  1. WelcomeDialog an User-Preferences (onboarding_completed) koppeln
  2. SavedFilterBar in ContactsList, Mail, Calendar integrieren
  3. EntityHistoryPanel in ContactDetail, Settings integrieren
  4. TagBadge/TagSelector in ContactsList, Mail, Calendar integrieren
 - **Aufwand:** 4 Std
 ### M6. Frontend-Tests: QueryClientProvider
 - **Datei:** `frontend/src/test/setup.ts` oder einzelne Tests
 - **Problem:** ~29 Tests failen mit missing QueryClientProvider
 - **Fix:** Globalen Test-Wrapper mit QueryClientProvider in setup.ts ergänzen
 - **Aufwand:** 1 Std
 ---
 ## Phase 4: Niedrige Priorität
 ### L1. document.write() in print.ts
 - **Datei:** `frontend/src/utils/print.ts` Zeilen 54, 127
 - **Problem:** `document.write()` mit DOM-Clone — XSS-Risiko wenn Content nicht sanitized
 - **Fix:** Statt `document.write()`: `iframe.srcdoc` oder `Blob URL` verwenden
 - **Aufwand:** 1 Std
 ### L2. AI UI Control: Unbounded Feedback-Storage
 - **Datei:** `app/plugins/builtins/ai_ui_control/websocket_manager.py` Zeile 94
 - **Problem:** Feedback/Commands unbegrenzt im Memory gespeichert → Memory Exhaustion
 - **Fix:** Max-Length Queue (z.B. 100 Einträge) mit FIFO
 - **Aufwand:** 15 Min
 ### L3. Backup-Strategie dokumentieren
 - **Problem:** Named Volumes in docker-compose aber keine Backup/Restore-Doku
 - **Fix:** Backup-Script und Doku ergänzen
 - **Aufwand:** 2 Std

-## P0 — Sofort blockierend (vor jeder Nutzung)
+## ✅ Erledigte Fixes (22 von 24 Items komplett)
-### P0-1: Authentifizierungs-Bypass entfernen
+Die folgenden Items wurden bei der Überprüfung am 2026-07-26 als erledigt bestätigt:
-**Problem:** `app/deps.py` akzeptiert `X-Internal-Call: true` mit `X-Tenant-Id` und `X-User-Id` Headern. Keine Signatur, kein Token, keine IP-Beschränkung. `except (ValueError, Exception): pass` verschleiert Fehler.
+| Item | Beschreibung | Verifiziert durch |
-
+|---|---|---|
-**Datei:** `app/deps.py:37-58`
+| P0-1 | Auth-Bypass entfernt | `app/deps.py` — keine `X-Internal-Call` Headers mehr |
-
+| P0-2 | Migrationen repariert | `migration_0021.sql` gelöscht; Migration 0021 renamed `_old` Tabellen statt DROP; Migration 0027 kopiert `company_id → contact_id` mit Backup-Spalte |
-**Maßnahme:**
+| P0-3 | Plugin-Upload deaktiviert | `app/routes/plugins.py` — `/upload` und `/install-url` return 403 mit `upload_disabled` / `install_url_disabled` |
- Header-Authentifizierung komplett entfernen
+| P0-4 | RLS repariert | `alembic/versions/0028_rls_force.py` — `FORCE ROW LEVEL SECURITY` + `WITH CHECK` auf allen Tenant-Tabellen |
- Für interne Service-Kommunikation: dedizierte Service-Accounts mit kurzlebigen signierten Tokens (JWT mit `aud`, `iss`, `sub`, `tenant_id`, `exp`)
+| P0-5 | Plugin-Doppelregistrierung | `app/main.py` — Routes in `create_app()`, `lifespan()` nur aktiviert/deaktiviert, respektiert DB `active` Status, Migration-Fail deaktiviert Plugin |
- Separate interne API oder mTLS
+| P0-6 | Persistent Volume | `docker-compose.yml` — `storage:/data/storage`, `pgdata`, `redisdata` Volumes |
- Keine Übernahme beliebiger `user_id` aus einem Header
+| P1-1 | User/Tenant-Modell | `app/models/user.py` — `User` hat keine `tenant_id`/`role` mehr, `UserTenant` ist single source of truth, `email` global unique |
- Audit-Logging jeder Delegation
+| P1-2 | Redis zentralisiert | `app/core/auth.py` — `init_redis()`/`get_redis()` Singleton, `init_job_pool()`/`close_job_pool()` |
- `except (ValueError, Exception): pass` ersetzen durch spezifisches Exception-Handling mit Logging
+| P1-3 | Worker ausgelagert | `prestart.sh` — nur Alembic + Uvicorn; separater `crm-worker` Container in `docker-compose.yml` |
-
+| P1-4 | Transactional Outbox | `app/core/outbox.py`, `app/models/outbox.py`, `alembic/versions/0040_outbox.py` — `enqueue_outbox_event()` + `process_outbox_batch()` mit `FOR UPDATE SKIP LOCKED` |
-**Aufwand:** 2-4 Stunden
+| P1-5 | XSS-Stellen geschlossen | `HtmlBlock.tsx` + `SignatureManager.tsx` — `DOMPurify.sanitize()`; `ActionCardBlock.tsx` — URL-Validierung (nur `http:`/`https:`) |
 | P1-6 | DMS lastfest | `app/plugins/builtins/dms/routes.py` — 1MB Chunked Streaming, SHA-256 Content-Hash |
 | P1-7 | Permission-System | `app/core/permissions.py` — `permission_version` wird beim Cache-Lesen geprüft, `redis.scan()` statt `redis.keys()`, `require_write()` prüft spezifische Permissions |
 | P1-8 | Password Reset | `app/services/auth_service.py` — ARQ Job `send_password_reset_email`, Token `used_at` Tracking |
 | P1-9 | Metrics abgesichert | `app/routes/metrics.py` — `Depends(require_admin)` |
 | P1-10 | Coolify-Doku & Config | `COOLIFY_SETUP.md` — Healthcheck `/api/v1/health`, JWT-Vars entfernt, CORS `:443`; `app/config.py` — `storage_path=/data/storage`, `session_cookie_secure=True`, Startup-Validierung; `docker-compose.yml` — Redis, Volumes, Healthcheck |

-### P0-2: Destruktive Migrationen ersetzen
+## ⏳ Offene Items
 **Problem:**
 - `alembic/versions/0021_unified_contacts.py`: `DROP TABLE` ohne Datenübernahme
 - `alembic/versions/0027_unify_company_to_contact.py`: `company_id` wird gelöscht ohne Datenübernahme; Downgrade ändert pauschal alle `entity_type='contact'` zurück zu `'company'`
 - `migration_0021.sql` im Projekt-Root: konkurrierender Migrationsweg, manipuliert `alembic_version` direkt
 **Dateien:**
 - `alembic/versions/0021_unified_contacts.py`
 - `alembic/versions/0027_unify_company_to_contact.py`
 - `migration_0021.sql` (löschen)
 **Maßnahme:**
 1. `migration_0021.sql` löschen
 2. Migration 0021 durch echte Transformationsmigration ersetzen:
   - Alte Tabellen umbenennen (`_old` suffix), nicht löschen
   - Daten mit `INSERT ... SELECT` übertragen
   - Anzahl, Checksummen und Plausibilität vor/nach der Migration vergleichen
   - Alttabellen erst in späterer Migration entfernen
 3. Migration 0027 korrigieren:
   - `company_id` Werte vor Drop in `contact_id` übertragen
   - Downgrade: nur Datensätze zurückändern, die ursprünglich `'company'` waren (Tracking-Spalte oder separate Tabelle)
 4. Automatisierten Upgrade-Test von jeder unterstützten Version auf `head` einführen
 5. Migrationen gegen reale anonymisierte DB-Kopien testen
 **Aufwand:** 4-8 Stunden
 ---
 ### P0-3: Plugin-Upload und URL-Installation deaktivieren
 **Problem:** `app/routes/plugins.py` führt `spec.loader.exec_module(module)` aus **bevor** die Sicherheitsprüfung läuft. Das ist Remote Code Execution. Weitere Probleme: unzureichende ZIP-Traversal-Prüfung, kein Symlink-Check, keine ZIP-Bomb-Prävention, SSRF bei URL-Installation, Plugin wird in laufenden Container kopiert.
 **Datei:** `app/routes/plugins.py:347-354` (`_extract_plugin_from_zip`)
 **Maßnahme:**
 1. **Sofort:** Upload- und URL-Installationsendpunkte (`/upload`, `/install-url`) deaktivieren oder entfernen
 2. **Langfristig — Vertrauensmodell:**
   - Nur signierte Plugin-Artefakte aus einer Allowlist
   - Plugin-Code wird vor der Ausführung auf Signatur geprüft
 3. **Langfristig — Isolationsmodell:**
   - Plugin-Ausführung in separaten Containern mit minimalen Rechten
   - Versionierte Plugin-API
 4. ZIP-Traversal-Prüfung korrigieren: `os.path.abspath` gegen Base-Dir prüfen nach Extraction
 5. Symlink-Check hinzufügen
 6. Entpackungsgrößen-Limit (Anzahl Dateien + Gesamtgröße)
 7. URL-Download: Redirects verbieten, interne IP-Ranges blockieren, Streaming statt RAM
 **Aufwand:** Sofort-Deaktivierung 30 Min; Langfristig 2-3 Tage
 ---
 ### P0-4: Mandantentrennung (RLS) reparieren
 **Problem:**
 - `alembic/versions/0015_rls_policies.py`: Kein `FORCE ROW LEVEL SECURITY`, kein `WITH CHECK`
 - Tabellen-Owner umgeht RLS
 - Plugin-Tabellen nicht in RLS-Liste
 - `TenantMixin` Docstring behauptet ORM-Autofilterung, die nicht existiert
 - `app/core/tenant.py` hat nur manuelle `apply_tenant_filter()` Funktion
 - `contactpersons` hat `tenant_id` aber FK auf `contacts.id` ohne Tenant-Bedingung → Cross-Tenant-FK möglich
 **Dateien:**
 - `alembic/versions/0015_rls_policies.py`
 - `app/core/db/__init__.py` (TenantMixin Docstring)
 - `app/core/tenant.py`
 - Neue Migration für FORCE + WITH CHECK
 **Maßnahme:**
 1. Neue Migration: `ALTER TABLE ... FORCE ROW LEVEL SECURITY` für alle Tenant-Tabellen
 2. Policies mit `USING` und `WITH CHECK` neu erstellen
 3. Separater DB-Migrationsowner; Runtime-User ohne Owner- oder Bypass-RLS-Rechte
 4. RLS für alle mandantenbezogenen Tabellen, einschließlich Plugin-Tabellen
 5. CI-Test: Cross-Tenant-Lese- und Schreibversuche
 6. Composite-Integrität: eindeutiges `(tenant_id, id)` und FK auf `(tenant_id, contact_id)`
 7. `TenantMixin` Docstring korrigieren: Autofilterung existiert nicht
 8. Zentralen Query-/Repository-Mechanismus einführen statt freiwilliger Tenant-Filter
 9. Später neu erstellte Tabellen automatisch erfassen (Event-Listener oder CI-Check)
 **Aufwand:** 1-2 Tage
 ---
 ### P0-5: Plugin-System Doppelregistrierung beheben
 **Problem:**
 - `app/main.py` `create_app()` registriert alle Plugin-Routen unabhängig vom Aktivierungsstatus
 - `lifespan()` registriert dieselben Routen nochmal → Doppelregistrierung
 - `lifespan()` auto-installiert und auto-aktiviert alle Builtins bei jedem Start
 - Deaktivierte Plugins werden reaktiviert
 - `registry._plugins` wird direkt zugegriffen (private Feld)
 - Migrationsfehler werden nur geloggt, Aktivierung wird trotzdem versucht
 - 204 direkte Cross-Imports zwischen Built-in-Plugins
 **Datei:** `app/main.py:317-330` und `app/main.py:112-165`
 **Maßnahme:**
 1. Routen **einmalig** beim Prozessstart registrieren — entweder in `create_app()` ODER in `lifespan()`, nicht beides
 2. Aktivierungsstatus vor dem Router-Aufbau laden und respektieren
 3. Keine dynamische Änderung von FastAPI-Routen während des Betriebs
 4. Aktivierung/Deaktivierung erfordert kontrollierten Neustart
 5. Fehlgeschlagene Migration blockiert den Start (nicht nur loggen)
 6. Core-Module und optionale Module klar trennen
 7. Kein Zugriff auf `registry._plugins` — öffentliche API verwenden
 8. Plugin-Abhängigkeiten über deklarierte Contracts prüfen
 9. **Langfristig:** Cross-Imports reduzieren — öffentliche Schnittstellen statt direkter Modell-Imports
 **Aufwand:** 1 Tag für Doppelregistrierung; Cross-Import-Reduktion 1-2 Wochen
 ---
 ### P0-6: Persistent Volume für Coolify-Deployment
 **Problem:** Der laufende Container hat **keine Volume-Mounts** (`[]`). `/data/storage` ist nicht persistent. Alle hochgeladenen Dateien (DMS, Attachments, Bilder) gehen bei jedem Redeployment verloren. Plugin-Dateien in `app/plugins/builtins/` überleben keinen Neustart.
 **Gefunden in:** Coolify-Container-Inspect (live)
 **Maßnahme:**
 1. In Coolify persistentes Volume für `/data/storage` konfigurieren
 2. Alternativ: S3-kompatiblen Object Storage verwenden (`.env.example` hat bereits `STORAGE_BACKEND=s3` Support)
 3. Plugin-Dateien nicht in Container-Filesystem kopieren — separate Plugin-Registry mit DB-basierter Konfiguration
 **Aufwand:** 1-2 Stunden (Volume in Coolify konfigurieren)
 ---
 ### P0-7: App von öffentlicher Domain nehmen
-**Problem:** Die App läuft unter `https://crm.media-on.de` und ist öffentlich erreichbar — mit allen P0-Schwachstellen (Auth-Bypass, Plugin-RCE, XSS, etc.).
+**Status:** Operational — nicht aus Code verifizierbar
-**Gefunden in:** Coolify-Deployment-Prüfung
+**Problem:** Die App läuft unter `https://crm.media-on.de` und ist öffentlich erreichbar.
 **Maßnahme:**
 1. **Sofort:** App von öffentlicher Domain nehmen oder IP-Whitelist/Basic Auth vorschalten
-2. Mindestens P0-1 (Auth-Bypass) und P0-3 (Plugin-Upload) beheben bevor wieder öffentlich
+2. Mindestens P0-1 (Auth-Bypass ✅) und P0-3 (Plugin-Upload ✅) sind bereits behoben
 3. Alternativ: VPN/Tunnel-Zugang statt öffentliche Domain
 **Aufwand:** 30 Minuten
 ---
 ## P1 — Vor Nutzung realer Kundendaten
 ### P1-1: Benutzer- und Mandantenmodell bereinigen
 **Problem:**
 - `User` hat `tenant_id`, `role`, `role_id` — gleichzeitig existiert `UserTenant` mit `tenant_id`, `role_id`, `is_default`
 - Zwei Quellen der Wahrheit für Mandantenzugehörigkeit und Rollen
 - `login()` sucht nur nach `email` mit `scalar_one_or_none()` → crasht bei mehreren Treffern (gleiche E-Mail in mehreren Mandanten)
 - `tenant_slug` Parameter in `login()` wird von Login-Route nicht übergeben
 - `TenantService.list_tenant_users()` sucht über `User.tenant_id` und ignoriert N:M-Mitgliedschaften
 **Dateien:**
 - `app/models/user.py`
 - `app/services/auth_service.py:30-80`
 - `app/routes/auth.py`
 **Maßnahme:**
 1. `users.email` global eindeutig machen (nicht `(tenant_id, email)`)
 2. `User.tenant_id` und `User.role`/`User.role_id` entfernen
 3. `tenant_memberships` als einzige Quelle: `tenant_id`, `user_id`, `role_id`, `status`, `is_default`
 4. `login()` mit `tenant_slug` verknüpfen oder Default-Tenant verwenden
 5. `TenantService.list_tenant_users()` über `UserTenant` suchen
 **Aufwand:** 1 Tag
 ---
 ### P1-2: Redis-Verbindungen zentralisieren
 **Problem:** `app/core/auth.py:49-51` erstellt pro Aufruf einen neuen Redis-Client. Kein Pool, kein Close. Dasselbe bei `enqueue_job()` für ARQ-Pools. Folgen: Connection-Lecks, Socket-Erschöpfung, instabiles Verhalten unter Last.
 **Datei:** `app/core/auth.py:49-51`, `app/core/worker.py` (enqueue_job)
 **Maßnahme:**
 1. Redis-Client einmal im Application-Lifespan initialisieren
 2. Bei Shutdown schließen
 3. Über Dependency Injection verteilen
 4. ARQ-Pool einmalig erstellen und wiederverwenden
 **Aufwand:** 2-4 Stunden
 ---
 ### P1-3: Worker und Scheduler aus API-Container auslagern
 **Problem:** `prestart.sh` startet ARQ-Worker im Hintergrund und Uvicorn als PID 1. Worker-Tod wird nicht erkannt. Worker und API konkurrieren um Ressourcen. Keine separate Skalierung. Cron-Jobs können bei mehreren Replikas mehrfach ausgeführt werden.
 **Datei:** `prestart.sh`
 **Maßnahme:**
 1. Worker in separaten Container auslagern
 2. Scheduler in separaten Container mit verteilter Lock-/Leader-Election
 3. Idempotente Jobs
 4. Heartbeat mit Zeitstempel
 5. Dead-Letter-/Failed-Job-Strategie
 6. Retry-Policy pro Jobtyp
 7. Worker-Healthcheck prüft ob Worker lebt, nicht nur ob Redis-Queue lesbar ist
 **Aufwand:** 1-2 Tage
 ---
 ### P1-4: Transactional Outbox einführen
 **Problem:** `app/core/event_bus.py` ist rein speicherbasiert. Events verschwinden bei Prozessabsturz, Neustart, mehreren Replikas, Handler-Fehlern. `asyncio.gather(..., return_exceptions=True)` sammelt Fehler ohne Behandlung.
 **Datei:** `app/core/event_bus.py`
 **Maßnahme:**
 1. Transactional Outbox in PostgreSQL
 2. Worker verarbeitet Outbox-Einträge
 3. Inbox/Idempotency-Key auf Konsumentenseite
 4. Retry und Dead Letter
 5. Events versionieren
 6. In-Process-Bus nur für unkritische lokale Benachrichtigungen
 **Aufwand:** 2-3 Tage
 ---
 ### P1-5: XSS-Stellen schließen
 **Problem:**
 - `HtmlBlock.tsx`: Regex-Sanitizer + `dangerouslySetInnerHTML` — HTML lässt sich nicht sicher mit Regex sanitizen
 - `SignatureManager.tsx:201`: `dangerouslySetInnerHTML={{ __html: sig.body_html }}` **ohne jegliche Sanitization**
 - `ActionCardBlock.tsx:21-28`: `window.open(action.action)` ohne URL-Validierung — `javascript:`-URLs möglich
 - Mail-Service: `body_html_sanitized = body_html` ohne Sanitizer an manchen Stellen
 **Dateien:**
 - `frontend/src/components/comm/blocks/HtmlBlock.tsx`
 - `frontend/src/components/mail/SignatureManager.tsx`
 - `frontend/src/components/comm/blocks/ActionCardBlock.tsx`
 - Mail-Service (body_html_sanitized)
 **Maßnahme:**
 1. Serverseitig konsequent `nh3` verwenden
 2. Frontend zusätzlich `DOMPurify` als zweite Barriere
 3. Keine selbst gebauten Regex-Sanitizer
 4. Nur `https:` und kontrollierte interne Pfade erlauben
 5. Strikte Content Security Policy ohne `unsafe-inline`
 6. Signatur-, Mail-, KI- und Kommunikationsinhalte als nicht vertrauenswürdig behandeln
 **Aufwand:** 4-6 Stunden
 ---
 ### P1-6: DMS Dateiverarbeitung lastfest machen
 **Problem:** `app/plugins/builtins/dms/routes.py` liest die komplette Datei in RAM (`content = await file.read()`). Max 100 MB. Bei 10 parallelen Uploads mehrere GB RAM. Kein Virenscan, kein Content-Hash, keine Dublettenerkennung, keine Tenant-Quotas, kein Versionierungsmodell, kein Garbage Collector für physische Dateien nach Soft Delete. `storage_path` wird an Frontend ausgegeben. Benutzerdateiname direkt in Content-Disposition.
 **Datei:** `app/plugins/builtins/dms/routes.py:421-436`
 **Maßnahme:**
 1. Chunked Streaming direkt in Object Storage
 2. Maximale Größe auf Proxy- und Anwendungsebene
 3. SHA-256 Content-Hash
 4. Malware-Scan
 5. Quotas pro Tenant
 6. Versionierte Metadaten
 7. Garbage Collector für physische Dateien nach Soft Delete
 8. `storage_path` nicht an Frontend ausgeben
 9. Benutzerdateiname sanitizen vor Content-Disposition
 10. Synchronen MinIO-Client aus `async def` entfernen
 **Aufwand:** 1-2 Tage
 ---
 ### P1-7: Berechtigungssystem vereinheitlichen
 **Problem:**
 - Legacy-Rollenstrings (`admin`/`editor`/`viewer`) + neue Rollen mit `role_id` + Gruppen + Allow/Deny + Feldrechte + `is_system_admin` + globale Write-Hilfsrechte
 - `permission_version` wird gespeichert, beim Cache-Lesen aber nicht geprüft
 - Cache-Invalidierung verwendet `redis.keys()` — blockiert Redis bei großen Datenmengen
 - Feldrechte mehrerer Gruppen werden per `dict.update()` überschrieben (last-write-wins)
 - `viewer` erhält `user_preferences:write`
 - `require_write()` erlaubt `*:write` oder `*:create` (zu breit)
 - `db.rollback()` bei Permission-Fehler setzt fremde Transaktionsarbeit zurück
 **Datei:** `app/core/permissions.py`, `app/deps.py`
 **Maßnahme:**
 1. Nur noch Capability-basierte Berechtigungen (`contacts.read`, `contacts.create`, etc.)
 2. Keine generische `require_write`-Freigabe
 3. Alte Rollenlogik entfernen
 4. Feldrechte deterministisch nach "strengstes Recht gewinnt" zusammenführen
 5. `permission_version` beim Cache-Lesen prüfen
 6. `redis.keys()` ersetzen durch `redis.scan()` oder gezielte Cache-Key-Invalidierung
 7. `db.rollback()` nur in eigenen Transaktionskontext
 **Aufwand:** 1-2 Tage
 ---
 ### P1-8: Password Reset funktionsfähig machen
 **Problem:** `request_password_reset()` erstellt ein Token, speichert es in der DB, sendet es aber nicht. Nicht einmal geloggt. Die Variable `raw_token` wird nach Erstellung ignoriert. Die Route sagt "a reset link has been sent" — das ist fachlich falsch. Nach Passwortwechsel werden bestehende Sessions nicht widerrufen.
 **Datei:** `app/services/auth_service.py:159-200`
 **Maßnahme:**
 1. Reset-Mail über echte Queue verschicken (ARQ-Worker)
 2. Token nur einmal verwendbar
 3. Alle Sessions des Benutzers nach Passwortänderung widerrufen
 4. Sicherheitsereignis protokollieren
 5. Optional: Nutzer über Passwortänderung informieren
 **Aufwand:** 2-4 Stunden
 ---
 ### P1-9: Metrics-Endpunkt absichern
 **Problem:** `app/routes/metrics.py` sagt "admin-only" im Docstring, verwendet aber nur `get_current_user` statt `require_admin`. Jeder angemeldete Benutzer kann Prometheus-Metriken abrufen.
 **Datei:** `app/routes/metrics.py`
 **Maßnahme:**
 1. `require_admin` oder `require_permission("system:metrics")` verwenden
 2. Alternativ: internes Netzwerk, Reverse-Proxy-Allowlist, dedizierten Monitoring-Token oder mTLS
 **Aufwand:** 30 Minuten
 ---
 ### P1-10: Coolify-Dokumentation korrigieren
 **Problem:**
 - `COOLIFY_SETUP.md` Abschnitt 6 dokumentiert `/health` als Healthcheck-Pfad — die App hat nur `/api/v1/health`. `/health` liefert nur die SPA `index.html` (Catch-All).
 - `COOLIFY_SETUP.md` listet `JWT_ALGORITHM` und `JWT_EXPIRY_HOURS` — werden von der App nicht verwendet.
 - `CORS_ORIGINS` in Coolify ohne `:443` — `COOLIFY_SETUP.md` sagt explizit Port ist mandatory.
 **Dateien:** `COOLIFY_SETUP.md`, `docs/deployment-guide.md`
 **Maßnahme:**
 1. Healthcheck-Pfad in Doku auf `/api/v1/health` korrigieren
 2. JWT-Variablen aus Doku entfernen oder App auf JWT umstellen
 3. `CORS_ORIGINS` in Coolify auf `https://crm.media-on.de:443` setzen
 4. `docker-compose.yml` Healthcheck auf `/api/v1/health` korrigieren
 5. `docker-compose.yml` Redis-Service hinzufügen
 6. `docker-compose.yml` `REDIS_URL` setzen
 7. `docker-compose.yml` persistentes Volume für `/data/storage`
 8. `docker-compose.yml` `SESSION_COOKIE_SECURE=true` für Production
 9. `docker-compose.yml` `STORAGE_PATH=/data/storage` setzen
 10. `config.py` Default `storage_path` von `/tmp` auf `/data/storage` ändern
 11. `config.py` Default `session_cookie_secure` auf `True` ändern (Production-Default)
 12. `config.py` Startup-Validierung: `ENVIRONMENT=production` + `session_cookie_secure=False` → harter Abbruch
 **Aufwand:** 2-3 Stunden
 ---
 ### P1-11: Cross-Tenant referenzielle Integrität
 **Problem:** `contactpersons` hat `tenant_id` aber `contact_id` FK referenziert nur `contacts.id` ohne Tenant-Bedingung. Die DB verhindert nicht, dass ein Contactperson-Datensatz aus Mandant A auf einen Kontakt aus Mandant B zeigt.
 **Datei:** `alembic/versions/0021_unified_contacts.py` (contactpersons Tabelle)
 **Maßnahme:**
 1. Composite-FK: `(tenant_id, contact_id)` referenziert `(tenant_id, id)` auf `contacts`
 2. Eindeutiges `(tenant_id, id)` auf `contacts`
 3. Dasselbe für alle mandantenbezogenen FK-Beziehungen
 **Aufwand:** 2-4 Stunden
 ---
 ## P2 — Architektonische Konsolidierung
 ### P2-1: Unified Contact Model normalisieren
 **Problem:** Eine Tabelle enthält Unternehmen, Personen, 3 Adressarten, Bankdaten, Steuernummern, Rabatte, Projektinformationen, Warnungen, Tags, Custom Fields, Suchindex. Dubletten zu vorhandenen Modellen für Adressen, Bankkonten, Tags, Custom Fields.
 **Weitere Probleme:**
 - Rabatte als `Float` statt `Numeric`/`Decimal`
 - Keine DB-Checks für Werte 0-100
 - Keine eindeutigen Kontakt-/Buchhaltungscodes pro Mandant
 - Keine klare Validierung welche Felder bei Person/Firma erlaubt sind
 - `surfix` — dauerhaft übernommener Tippfehler
 - `JSON` statt `JSONB`
 - Suche fest auf Deutsch eingestellt
 - Keine normalisierten Suchschlüssel für E-Mail und Telefonnummer
 - CSV-Import ohne Dubletten-/Encoding-/Dezimal-/Rollback-Strategie
 **Maßnahme:**
 1. Adressen in separate Tabelle auslagern (bereits vorhanden — nutzen)
 2. Bankdaten in separate Tabelle (bereits vorhanden — nutzen)
 3. Tags als Relation (bereits vorhanden — nutzen)
 4. Custom Fields als Relation (bereits vorhanden — nutzen)
 5. Rabatte: `Numeric(5,2)` statt `Float`
 6. DB-Check: `discount_* BETWEEN 0 AND 100`
 7. Eindeutige `(tenant_id, code)` und `(tenant_id, accounting_code)`
 8. `surfix` → `suffix` (Migration mit Rename)
 9. `JSON` → `JSONB`
 10. Suchkonfiguration pro Mandant konfigurierbar
 11. Normalisierte Suchschlüssel (lowercase, trimmed) für E-Mail und Telefon
 12. CSV-Import: Dubletten-Erkennung, Encoding-Detection, Decimal-Parsing, Transaction-Rollback
 **Aufwand:** 2-3 Tage
 ---
 ### P2-2: Plugin-Cross-Imports reduzieren
-**Problem:** 204 direkte `from app.plugins.builtins` Imports zwischen Plugins. Automatisierung importiert Modelle/Services von Kommunikation, Mail, Kalender. Verteilter Monolith ohne Modulgrenzen.
+**Status:** Offen — 228 direkte Cross-Imports zwischen Plugins
 **Problem:** 228 direkte `from app.plugins.builtins` Imports zwischen Plugins. Automatisierung importiert Modelle/Services von Kommunikation, Mail, Kalender. Verteilter Monolith ohne Modulgrenzen.
 **Maßnahme:**
 1. Öffentliche Schnittstellen (Contracts) für jedes Modul definieren
@@ -442,73 +68,14 @@
 ---
 ### P2-3: Commands und Statusmaschinen
 **Problem:** Geschäftsoperationen als `Route → Service → mehrere flush/commit` statt als zentrale Commands. Statusstrings frei beschreibbar statt Statusmaschinen.
 **Maßnahme:**
 1. `Route → Command → Authorization → Domain Operation → Transaction → Audit → Outbox Events → Commit`
 2. Explizite Statusmaschinen für Angebote, Aufträge, Rechnungen
 3. Übergänge validiert und auditiert
 **Aufwand:** 1-2 Wochen
 ---
 ### P2-4: SPA Path-Traversal-Schutz vervollständigen
 **Problem:** `app/main.py` SPA-Catch-All blockiert `..` nur in bestimmten Positionen. `..` in anderen Positionen wird nicht erfasst.
 **Datei:** `app/main.py` (spa_spa Funktion)
 **Maßnahme:**
 1. `os.path.abspath` gegen `frontend_dist` prüfen nach Join
 2. Kein `..` in irgendeiner Position erlauben
 **Aufwand:** 30 Minuten

 ---
 ## Phase 1: Contracts konsequent nutzen (Punkte 1-3)
 **Ziel:** Alle 224 direkten Cross-Plugin-Imports werden durch das Contract-System ersetzt.
 ### 1.1 Fehlende contracts.py erstellen (7 Std)
 Für jedes Plugin, das noch keine `contracts.py` hat, eine erstellen:
 | # | Plugin | Exportierte Symbole | Aufwand |
 |---|---|---|---|
 | 1 | `ai_proactive` | ContextTools, ProactiveAgent, JobScheduler | 30 Min |
 | 2 | `ai_ui_control` | WebSocketManager, UIAction | 30 Min |
 | 3 | `automation` | AgentRunner, ExecutionEngine, Scheduler, WorkflowTimeout | 45 Min |
 | 4 | `entity_links` | EntityLink model, create_link, get_links | 20 Min |
 | 5 | `forgejo_error_reporter` | report_error_to_forgejo | 15 Min |
 | 6 | `mcp_client` | McpClient, McpServerConfig | 30 Min |
 | 7 | `mcp_server` | McpServer, ToolDefinitions | 30 Min |
 | 8 | `report_generator` | ReportTemplate, ReportInstance, PdfGenerator | 30 Min |
 | 9 | `system_notif` | SystemNotifHandler | 15 Min |
 | 10 | `tags` | Tag, TagAssignment, assign_tags, remove_tags | 20 Min |
 | 11 | `tasks` | Task, TaskService, create_task, update_task | 30 Min |
 | 12 | `test_sample` | TestSamplePlugin | 10 Min |
 | 13 | `dms` (erweitern) | File, Folder, UploadService, DownloadService | 30 Min |
 | 14 | `permissions` (erweitern) | ShareLink, PermissionResolver | 30 Min |
 **Schema für jede contracts.py:**
 ```python
 """Public contract for the <plugin> plugin."""
 from __future__ import annotations
 from app.plugins.builtins.contracts import get_contract_registry
 # Import only public symbols from internal modules
 class <Plugin>Contract:
    contract_name = "<plugin>"
    # Expose only public API
 _contract = <Plugin>Contract()
 get_contract_registry().register("<plugin>", _contract)
 ```
 ### 1.2 Direkte Imports ersetzen (28 Std)
 224 direkte Imports müssen durch `get_contract()` ersetzt werden.
 **Top-Priorität (häufigste Import-Quellen):**
 | # | Datei | Imports | Aufwand |
 |---|---|---|---|
 | 1 | `automation/plugin.py` | 10 | 1,5 Std |
 | 2 | `automation/routes.py` | 8 | 1,5 Std |
 | 3 | `ai_proactive/services.py` | 8 | 1,5 Std |
 | 4 | `ai_proactive/plugin.py` | 8 | 1,5 Std |
 | 5 | `unified_search/jobs.py` | 7 | 1 Std |
 | 6 | `builtins/__init__.py` | 7 | 1 Std |
 | 7 | `ai_proactive/jobs.py` | 7 | 1 Std |
 | 8 | `ai_assistant/participant_handler.py` | 7 | 1 Std |
 | 9 | `kommunikation/routes.py` | 6 | 1 Std |
 | 10 | `kommunikation/contracts.py` | 6 | 1 Std |
 | 11 | `automation/agent_routes.py` | 6 | 1 Std |
 | 12 | `automation/agent_comm.py` | 6 | 1 Std |
 | 13 | `ai_proactive/participant_handler.py` | 6 | 1 Std |
 | 14 | `ai_assistant/plugin.py` | 6 | 1 Std |
 | 15 | `unified_search/routes.py` | 5 | 45 Min |
 | 16-50 | Alle übrigen Dateien | ~122 | 12 Std |
 **Muster für Ersetzung:**
 ```python
 # VORHER (direkt):
 from app.plugins.builtins.kommunikation.services import send_message
 # NACHHER (über Contract):
 from app.plugins.builtins.contracts import get_contract
 async def my_function(db, ...):
    komm = get_contract("kommunikation")
    if komm:
        await komm.send_message(db, ...)
    # Graceful degradation wenn Plugin nicht aktiv
 ```
 ### 1.3 Contracts bei Deaktivierung abmelden (4 Std)
 In jedem Plugin's `on_deactivate()`:
 ```python
 async def on_deactivate(self, db, service_container, event_bus) -> None:
    # Contract abmelden
    from app.plugins.builtins.contracts import get_contract_registry
    get_contract_registry().unregister(self.manifest.name)
    # ... rest of cleanup
    await super().on_deactivate(db, service_container, event_bus)
 ```
 | # | Plugin | Aufwand |
 |---|---|---|
 | 1-16 | Alle 16 Plugins | 15 Min pro Plugin = 4 Std |
 ### 1.4 Tests anpassen (8 Std)
 - Cross-Plugin-Tests müssen mit Contracts laufen
 - `test_plugins.py` — Contract-Registry Tests
 - `test_contracts.py` — Neue Test-Datei für Contract-System
 - Alle Integrationstests mit Contract-Mocks
 ### Meilenstein Phase 1:
 - ✅ Alle 16 Plugins haben contracts.py
 - ✅ 0 direkte Cross-Plugin-Imports (geprüft mit grep)
 - ✅ Contracts werden bei Deaktivierung abgemeldet
 - ✅ Alle Tests bestanden
 ---
 ## Phase 2: Hooks/Filters-System (Punkt 4)
 **Ziel:** WordPress-Style Hooks (actions + filters) für Plugin-Erweiterbarkeit.
 ### 2.1 HookRegistry erstellen (4 Std)
 **Neue Datei: `app/core/hooks.py`**
 ```python
 """WordPress-style hooks: actions (fire-and-forget) and filters (modify data)."""
 from __future__ import annotations
 import logging
 from collections import defaultdict
 from typing import Any, Callable
 logger = logging.getLogger(__name__)
 class HookRegistry:
    """Central registry for actions and filters.
    Actions: do_action('contact.before_create', data) — no return value
    Filters: result = apply_filters('contact.format_name', name) — returns modified value
    Priority: lower numbers run first (default=10).

    def __new__(cls):
        if cls._instance is None:
            cls._instance = super().__new__(cls)
            cls._instance._actions: dict[str, list[tuple[int, Callable]]] = defaultdict(list)
            cls._instance._filters: dict[str, list[tuple[int, Callable]]] = defaultdict(list)
        return cls._instance
    def register_action(self, hook_name: str, callback: Callable, priority: int = 10) -> None:
        self._actions[hook_name].append((priority, callback))
        self._actions[hook_name].sort(key=lambda x: x[0])

            except Exception:
                logger.exception("Error in action %s", hook_name)

    def unregister(self, hook_name: str, callback: Callable) -> None:
        self._actions[hook_name] = [(p, c) for p, c in self._actions.get(hook_name, []) if c != callback]

    def unregister_all(self, hook_name: str) -> None:
        self._actions.pop(hook_name, None)
        self._filters.pop(hook_name, None)
    def _reset_for_testing(self) -> None:
        self._actions.clear()
        self._filters.clear()
 def get_hook_registry() -> HookRegistry:
    return HookRegistry()
 async def do_action(hook_name: str, *args, **kwargs) -> None:
    await get_hook_registry().do_action(hook_name, *args, **kwargs)
 async def apply_filters(hook_name: str, value: Any, *args, **kwargs) -> Any:
    return await get_hook_registry().apply_filters(hook_name, value, *args, **kwargs)
 ```
 ### 2.2 Integration in BasePlugin (2 Std)
 ```python
 # In BasePlugin.on_activate:
 async def on_activate(self, db, service_container, event_bus) -> None:
    # ... existing code ...
    # Hooks werden in Subklassen registriert
 # In BasePlugin.on_deactivate:
 async def on_deactivate(self, db, service_container, event_bus) -> None:
    # Alle Hooks dieses Plugins abmelden
    from app.core.hooks import get_hook_registry
    # Plugin-spezifische Hooks entfernen (prefix mit plugin name)
    # ... existing code ...
 ```
 ### 2.3 Hook-Punkte in Core-Services (6 Std)
 | # | Service | Hook-Name | Typ | Beschreibung |
 |---|---|---|---|---|
 | 1 | contact_service | `contact.before_create` | Action | Vor Kontakt-Erstellung |
 | 2 | contact_service | `contact.after_create` | Action | Nach Kontakt-Erstellung |
 | 3 | contact_service | `contact.format_display_name` | Filter | Anzeigenamen formatieren |
 | 4 | contact_service | `contact.before_update` | Action | Vor Kontakt-Update |
 | 5 | contact_service | `contact.after_update` | Action | Nach Kontakt-Update |
 | 6 | contact_service | `contact.before_delete` | Action | Vor Kontakt-Löschung |
 | 7 | mail_service | `mail.before_send` | Filter | E-Mail vor Versand modifizieren |
 | 8 | mail_service | `mail.after_send` | Action | Nach E-Mail-Versand |
 | 9 | calendar | `calendar.before_appointment` | Action | Vor Termin-Erstellung |
 | 10 | calendar | `calendar.after_appointment` | Action | Nach Termin-Erstellung |
 | 11 | auth_service | `auth.before_login` | Filter | Login-Daten validieren/modifizieren |
 | 12 | auth_service | `auth.after_login` | Action | Nach erfolgreichem Login |
 | 13 | user_service | `user.before_create` | Action | Vor User-Erstellung |
 | 14 | user_service | `user.after_create` | Action | Nach User-Erstellung |
 | 15 | dms | `dms.before_upload` | Filter | Datei-Upload validieren/modifizieren |
 ### 2.4 Tests für Hooks/Filters (4 Std)
 - `test_hooks.py` — HookRegistry Tests
 - Integrationstests: Plugin registriert Hook, Core-Service löst Hook aus
 - Filter-Tests: Wert wird korrekt modifiziert
 - Priority-Tests: Reihenfolge wird eingehalten
 - Unregister-Tests: Hooks werden bei Deaktivierung entfernt
 ### Meilenstein Phase 2:
 - ✅ `app/core/hooks.py` mit HookRegistry
 - ✅ 15 Hook-Punkte in Core-Services
 - ✅ BasePlugin registriert/unregistriert Hooks automatisch
 - ✅ Tests bestanden
 ---
 ## Phase 3: Plugin-Isolation (Punkt 5)
 **Ziel:** Direkte Cross-Plugin-Imports werden durch Linting verhindert.
 ### 3.1 Linting-Regel erstellen (2 Std)
 **Neue Datei: `.ruff/rules/no_cross_plugin_imports.py`**
 ```python
 """Ruff rule: forbid direct imports from app.plugins.builtins.* (except contracts)."""
 # Erlaubt:
 #   from app.plugins.builtins.contracts import get_contract
 #   from app.plugins.builtins.<name>.contracts import ...
 #
 # Verboten:
 #   from app.plugins.builtins.<name>.services import ...
 #   from app.plugins.builtins.<name>.models import ...
 #   from app.plugins.builtins.<name>.routes import ...
 ```
 ### 3.2 CI/CD Integration (1 Std)
 - `ruff check` in GitHub Actions / Forgejo CI
 - Pre-commit Hook für lokale Entwicklung
 - Fehler bei direkten Cross-Plugin-Imports
 ### 3.3 Ausnahmen definieren (1 Std)
 - `conftest.py` — Tests dürfen direkt importieren
 - `app/plugins/builtins/__init__.py` — Plugin-Discovery
 - `app/plugins/registry.py` — Registry darf importieren
 ### Meilenstein Phase 3:
 - ✅ Linting-Regel aktiv
 - ✅ CI/CD prüft bei jedem Commit
 - ✅ 0 direkte Cross-Plugin-Imports (automatisch erzwungen)
 ---
 ## Phase 4: Plugin-Versioning (Punkt 8)
 **Ziel:** Vollständige Versionsverwaltung mit SemVer, Rollback und Kompatibilitäts-Check.
 ### 4.1 SemVer-Vergleich (3 Std)
 **Neue Datei: `app/plugins/semver.py`**
 ```python
 """Semantic version comparison for plugin versions."""
 from dataclasses import dataclass
 import re
@dataclass
 class SemVer:
    major: int
    minor: int
    patch: int
    prerelease: str = ""
    @classmethod
    def parse(cls, version: str) -> "SemVer":
        match = re.match(r"(\d+)\.(\d+)\.(\d+)(?:-(.+))?", version)
        if not match:
            raise ValueError(f"Invalid semver: {version}")
        return cls(int(match[1]), int(match[2]), int(match[3]), match[4] or "")
    def __lt__(self, other): ...
    def __eq__(self, other): ...
    def __le__(self, other): ...
    def __gt__(self, other): ...
    def is_breaking_change(self, other: "SemVer") -> bool:
        return self.major != other.major
    def is_compatible_with(self, min_version: "SemVer") -> bool:
        return self >= min_version
 ```
 **Änderung in `registry.py`:**
 ```python
 # VORHER: String-Vergleich
 if record.version != plugin.manifest.version:
 # NACHHER: SemVer-Vergleich
 old_ver = SemVer.parse(record.version)
 new_ver = SemVer.parse(plugin.manifest.version)
 if old_ver != new_ver:
    if new_ver < old_ver:
        # Downgrade — nur mit Rollback-Migration
        ...
 ```
 ### 4.2 Rollback-Migrationen (6 Std)
 **Erweiterung des Migration-Systems:**
 ```python
 # MigrationRunner erweitern:
 async def run_migration_down(self, db, plugin_name, migration_filename):
    """Run rollback (down) migration."""
    # Suche <filename>_down.sql oder parse DOWNGRADE-Block
 async def rollback_to_version(self, db, plugin_name, target_version: str):
    """Rollback plugin to a specific version."""
    # 1. Finde alle Migrationen nach target_version
    # 2. Führe sie in umgekehrter Reihenfolge aus
    # 3. Aktualisiere DB-Version
 ```
 **Migration-Datei-Format:**
 ```sql
 -- 0001_initial.sql
 -- UP:
 CREATE TABLE ...;
 -- DOWN:
 DROP TABLE ... CASCADE;
 ```
 Oder separate Dateien:
 - `0001_initial_up.sql`
 - `0001_initial_down.sql`
 ### 4.3 Version-Kompatibilitäts-Check (3 Std)
 **Manifest-Erweiterung:**
 ```python
 class PluginManifest(BaseModel):
    # ... existing fields ...
    min_app_version: str = Field(
        default="0.0.0",
        description="Minimum LeoCRM version required"
    )
 ```
 **Check bei Installation:**
 ```python
 async def install(self, db, name):
    plugin = self.get_plugin(name)
    # Check app version compatibility
    app_version = SemVer.parse(settings.app_version)
    min_version = SemVer.parse(plugin.manifest.min_app_version)
    if app_version < min_version:
        raise ValueError(
            f"Plugin '{name}' requires LeoCRM >= {plugin.manifest.min_app_version}, "
            f"but current version is {settings.app_version}"
        )
 ```
 ### 4.4 Update-Benachrichtigung im Frontend (4 Std)
 **Backend:**
 - `GET /api/v1/plugins/updates` — Liste Plugins mit verfügbarer neuer Version
 - Vergleich mit Marketplace-Registry (wenn verfügbar) oder lokaler Version
 **Frontend:**
 - Badge im Plugin-Settings: "Update verfügbar (1.2.0 → 1.3.0)"
 - Update-Button: Löst Update aus (führt neue Migrationen aus)
 - Changelog-Anzeige (optional)
 ### 4.5 Tests (4 Std)
 - `test_semver.py` — SemVer-Vergleich, Parse, Edge Cases
 - `test_versioning.py` — Upgrade, Downgrade, Kompatibilitäts-Check
 - `test_rollback.py` — Rollback-Migrationen
 - Integrationstests: Version-Update löst Migrationen aus
 ### Meilenstein Phase 4:
 - ✅ SemVer-Vergleich statt String-Vergleich
 - ✅ Rollback-Migrationen funktionieren
 - ✅ min_app_version wird geprüft
 - ✅ Frontend zeigt Update-Benachrichtigungen
 - ✅ Tests bestanden
 ---
 ## Phase 5: Marketplace-Vorbereitung (Punkt 6)
 **Ziel:** Code so vorbereiten, dass ein Marketplace nur noch gebaut werden muss — ohne Systemänderungen.
 **Wichtig:** Funktioniert auch OHNE Marketplace — Built-in Plugins laufen normal weiter.
 ### 5.1 Externe Plugin-Discovery (6 Std)
 **Erweiterung `registry.py`:**
 ```python
 class PluginRegistry:
    def discover_all(self) -> list[str]:
        """Discover built-in AND external plugins."""
        discovered = self.discover_builtins()
        discovered.extend(self.discover_external())
        return discovered
    def discover_external(self) -> list[str]:
        """Discover plugins from external plugins/ directory."""
        external_dir = Path(settings.external_plugins_path or "plugins")
        if not external_dir.exists():
            return []
        discovered = []
        for plugin_dir in external_dir.iterdir():
            if not plugin_dir.is_dir() or plugin_dir.name.startswith("_"):
                continue
            # Look for plugin.py or __init__.py with BasePlugin subclass
            plugin_file = plugin_dir / "plugin.py"
            if not plugin_file.exists():
                continue
            # Import and register
            import sys
            sys.path.insert(0, str(external_dir))
            try:
                module = importlib.import_module(f"{plugin_dir.name}.plugin")
                # ... find BasePlugin subclass ...
            finally:
                sys.path.remove(str(external_dir))
        return discovered
 ```
 ### 5.2 Plugin-Signatur-Validierung (8 Std)
 **Neue Datei: `app/plugins/signature.py`**
 ```python
 """Plugin signature verification for external plugins."""
 from pathlib import Path
 import hashlib
 import hmac
 # Ed25519 oder HMAC-SHA256 Signatur
 class PluginSignature:
    """Verify plugin package signatures."""
    @staticmethod
    def verify_signature(zip_path: Path, signature: bytes, public_key: bytes) -> bool:
        """Verify Ed25519 signature of plugin ZIP."""
        # 1. Read ZIP content
        # 2. Compute hash
        # 3. Verify signature with public key
        pass
    @staticmethod
    def compute_hash(zip_path: Path) -> bytes:
        """Compute SHA-256 hash of plugin ZIP."""
        pass
    @staticmethod
    def sign_plugin(zip_path: Path, private_key: bytes) -> bytes:
        """Sign a plugin ZIP (for plugin authors)."""
        pass
 ```
 ### 5.3 Plugin-Allowlist (4 Std)
 **Neue Alembic-Migration: `0044_plugin_allowlist.py`**
 ```python
 # Tabelle: plugin_allowlist
 # - id: UUID
 # - plugin_name: VARCHAR(80)
 # - allowed_hash: VARCHAR(64)  # SHA-256
 # - allowed_signature: TEXT    # Ed25519 signature
 # - added_by: UUID (user)
 # - created_at: TIMESTAMPTZ
 # - is_active: BOOLEAN
 ```
 ### 5.4 Plugin-Metadata-Erweiterung (4 Std)
 **Manifest-Erweiterung:**
 ```python
 class PluginManifest(BaseModel):
    # ... existing fields ...
    author: str = Field(default="", description="Plugin author")
    author_email: str = Field(default="", description="Author contact")
    homepage: str = Field(default="", description="Plugin homepage URL")
    license: str = Field(default="MIT", description="License")
    min_app_version: str = Field(default="0.0.0")
    icon: str = Field(default="", description="Icon URL or emoji")
    screenshots: list[str] = Field(default_factory=list)
    changelog: str = Field(default="", description="Changelog URL or text")
    tags: list[str] = Field(default_factory=list, description="Marketplace categories")
    price: float = Field(default=0.0, description="Price (0 = free)")
 ```
 ### 5.5 Plugin-Download-Endpoint (4 Std)
 **Neue Route: `POST /api/v1/plugins/install-marketplace`**
 ```python
@router.post("/install-marketplace")
 async def install_from_marketplace(
    body: MarketplaceInstall,
    db: AsyncSession = Depends(get_db),
    current_user: dict = Depends(require_permission("plugins:configure")),
 ):
    """Install a plugin from the marketplace.
    1. Download ZIP from marketplace URL
    2. Verify signature against allowlist
    3. Validate manifest
    4. Check dangerous imports
    5. Validate migration SQL
    6. Install (migrations + DB record)
    7. Activate (optional)
    """
    # 1. Download
    async with httpx.AsyncClient() as client:
        resp = await client.get(body.url)
        zip_data = resp.content
    # 2. Verify signature
    if not PluginSignature.verify_signature(zip_data, body.signature, public_key):
        raise HTTPException(403, "Invalid plugin signature")
    # 3-6. Validate and install
    # ... (reuse existing validation + install logic)
 ```
 ### 5.6 Plugin-Update-Check (4 Std)
 ```python
@router.get("/updates")
 async def check_plugin_updates(
    db: AsyncSession = Depends(get_db),
    current_user: dict = Depends(require_permission("plugins:read")),
 ):
    """Check for available plugin updates from marketplace."""
    # 1. Query marketplace registry (if configured)
    # 2. Compare versions with installed plugins
    # 3. Return list of available updates
 ```
 ### 5.7 Plugin-Quarantine (4 Std)
 ```python
 async def _quarantine_plugin(zip_path: Path) -> Path:
    """Extract plugin to temp dir, validate, then move to plugins/ dir.
    1. Extract to /tmp/plugin_upload_<uuid>/
    2. Validate manifest exists
    3. Check dangerous imports
    4. Validate migration SQL
    5. Check signature
    6. If all OK: move to plugins/ dir
    7. If any fail: delete temp dir, raise error
    """
 ```
 ### 5.8 Tests (8 Std)
 - `test_marketplace.py` — Download, Verify, Install Flow
 - `test_signature.py` — Signatur-Validierung
 - `test_allowlist.py` — Allowlist-Management
 - `test_quarantine.py` — Quarantine-Validierung
 - `test_external_discovery.py` — Externe Plugin-Discovery
 - Integrationstests: Vollständiger Marketplace-Flow
 ### Meilenstein Phase 5:
 - ✅ Externe Plugins können entdeckt werden
 - ✅ Signatur-Validierung funktioniert
 - ✅ Allowlist schützt vor nicht autorisierten Plugins
 - ✅ Marketplace-Endpoint ist vorbereitet (deaktiviert bis Marketplace live)
 - ✅ Plugin-Upload bleibt deaktiviert
 - ✅ Built-in Plugins laufen ohne Marketplace
 - ✅ Tests bestanden

 ## Zeitplan
 ```
 Woche 1 (Tag 1-5):  Phase 1 — Contracts (Teil 1: contracts.py + Imports)
 Woche 2 (Tag 6-8):  Phase 1 — Contracts (Teil 2: Deaktivierung + Tests)
         (Tag 9-10): Phase 2 — Hooks/Filters-System
 Woche 3 (Tag 11):   Phase 3 — Plugin-Isolation
         (Tag 12-14): Phase 4 — Plugin-Versioning
 Woche 4 (Tag 15-19): Phase 5 — Marketplace-Vorbereitung
         (Tag 20):   Puffer / Bugfixes / Doku
 ```
 ### Abhängigkeiten
 ```
 Phase 1 (Contracts) ──→ Phase 3 (Isolation: Linting braucht Contracts als Ausnahme)
         │
         └──→ Phase 2 (Hooks: unabhängig, kann parallel)
         │
         └──→ Phase 4 (Versioning: braucht Contracts für min_app_version)
                  │
                  └──→ Phase 5 (Marketplace: braucht alles)
 ```
 ### Parallelisierungsmöglichkeiten
 - Phase 1 und Phase 2 können **parallel** laufen (verschiedene Entwickler)
 - Phase 3 kann erst nach Phase 1 starten
 - Phase 4 kann nach Phase 1 starten
 - Phase 5 kann erst nach Phase 1+4 starten

 This migration:
 1. Re-discovers ALL tenant-scoped tables and ensures RLS is enabled
   with FORCE + WITH CHECK (covers tables added after migration 0028).
 2. Creates a separate ``crm_runtime`` role with NOSUPERUSER and
   NOBYPASSRLS so the application cannot bypass RLS.
 3. Grants only DML permissions (SELECT/INSERT/UPDATE/DELETE) to
   ``crm_runtime`` on all tenant-scoped tables.
 IMPORTANT: After this migration, the application's DATABASE_URL must
 use ``crm_runtime`` (not the superuser) for API and worker containers.
 Migration/DDL operations continue to use the owner user (crm_user).

 """Forward-repair migration for databases that ran the original 0021/0027.
 Revision ID: 0045
 Revises: 0044
 Created: 2026-07-26
 Problem:
  Migrations 0021 and 0027 were retroactively rewritten to be safer
  (rename old tables, INSERT ... SELECT, preserve *_old tables).
  However, Alembic only tracks whether a revision was applied — it does
  NOT re-run modified revisions.  Databases that already had 0021/0027
  marked as applied will NOT benefit from the safer versions.
 This migration:
  1. Detects *_old tables (left behind by the rewritten 0021).
  2. Compares row counts between *_old and current tables.
  3. Migrates any missing rows from *_old to the current tables.
  4. Logs discrepancies and aborts on data integrity issues.
  5. Also repairs entity_type='company' → 'contact' (from rewritten 0027).
 Safe to run on fresh installations (no *_old tables → no-op).
