fix(csp): frame-ancestors auf 'self' – PDF-Vorschau-iframe ging nicht

Das CSP `frame-ancestors 'none'` blockte ALLE iframe-Embeddings, auch
same-origin – damit ließ sich die annotierte PDF-Vorschau im Editor für
PDF-Auftragsvorlagen nicht laden. Browser zeigten je nach Variante
"Verbindung abgelehnt" oder einen CSP-Violation-Fehler.

CSP überschreibt X-Frame-Options, der alte SAMEORIGIN-Header reichte also
nicht aus. Auf 'self' wechseln: eigene App darf eigene Resourcen embeden,
externe Sites weiterhin gesperrt (was X-Frame-Options bereits regelt).

+| `./data/backups/` | DB-Backups (`npm run db:backup`) |
+
+Ports + Pfade konfigurierst du in `./.env` (Default-Werte siehe `.env.example`).
+
+> **Erste Inbetriebnahme:** In der `.env` einmalig `RUN_SEED=true` setzen,
+> `docker compose up -d` ausführen, dann wieder auf `false`. Danach existiert
+> der initiale Admin-User `admin@admin.com` / `admin`.

+Es gibt drei Pfade, je nachdem wo die ZIP gerade liegen soll:
+
+| Wo | Pfad | Wann |
+|---|---|---|
+| **Laufende DB einer Instanz** | UI-Upload oder `./factory-import.sh` | Bestehende Live-Instanz updaten |
+| **Drop-Box im Repo** (`factory-exports/`) | `./factory-export.sh` legt ab, `./factory-import.sh` liest | Transfer zwischen dev und prod via `scp` |

+# 🛡️ Security-Hardening – die ganze Geschichte
+
+Dokumentiert die acht Hardening-Runden, die OpenCRM zwischen erster
+Code-Review und öffentlichem Deployment durchlaufen hat.
+
+Format pro Runde: **Was war kaputt** → **Wie es gefixt wurde** → wo möglich
+**Live-Test-Resultate**.
+
+> Die ersten beiden Runden gibt es zusätzlich als ausführlicheren Review in
+> [SECURITY-REVIEW.md](./SECURITY-REVIEW.md).
+
+---
+
+## 📊 Live-verifizierte Tests im Überblick
+
+Die wichtigsten Schwachstellen wurden mit echten HTTP-Requests gegen den Dev-Server
+durchgespielt – statisches Code-Review fand ca. 70 % der Findings, die letzten 30 %
+brauchten Live-Tests.
+

+
+## 🗂️ Runde-für-Runde
+
+### Runde 1 – Erste kritische Findings (statisches Review)
+
+- CORS komplett offen → `CORS_ORIGINS` explizit
+- Keine Security-Headers → Helmet aktiviert (HSTS, X-Frame-Options, nosniff …)
+- JWT-Fallback-Secret entfernt → Fail-Fast beim Start (≥ 32 Zeichen JWT_SECRET, 64-Hex ENCRYPTION_KEY)
+- IDOR bei 7 Contract-Endpoints (`canAccessContract`)
+- XSS via Email-Body → DOMPurify mit strikter Config
+- Customer-API: Passwort-Hashes in API-Responses → Sanitizer
+- Portal-JWT-Invalidation nach Passwort-Reset (`portalTokenInvalidatedAt`)
+- Body-Size-Limit 5 MB
+
+### Runde 2 – Deep-Dive (parallele Audit-Agents)
+
+- **Zip-Slip im Backup-Upload** (Arbitrary File Write) → Pfad-Validation
+- **Mass Assignment bei Customer/User** (Privilege Escalation via `roleIds`!) → Whitelist-Picker
+- 13 weitere IDOR-Stellen (Meter-Readings, Email-Anhänge, StressfreiEmail-Credentials …)
+- Path-Traversal bei Backup-Name und GDPR-Proof-Download → Regex/Safelist
+
+### Runde 3 – Tiefer Dive (8 weitere Hardenings)
+
+- JWT algorithm confusion: `jwt.verify(..., { algorithms: ['HS256'] })`
+- `trust proxy = 1` für Rate-Limiter hinter Reverse-Proxy
+- IDOR Invoice (`/api/energy-details/:ecdId/invoices`) → `canAccessEnergyContractDetails`
+- IDOR PDF-Template-Generator → `canAccessContract`
+- Email-Anhang-Download: Content-Type-Safelist (HTML/SVG nie inline) + `X-Content-Type-Options: nosniff` + Filename-CRLF-Sanitizing
+- Provider/Tariff-GETs: `requirePermission('providers:read')` (Portal-Kunden sehen Provider-Liste nicht mehr)
+- SMTP-Header-Injection: zentrale CRLF-Validierung in `smtpService.sendEmail`
+- bcrypt cost 10 → 12 (OWASP 2026)
+
+### Runde 4 – Live-Tests gegen Dev-Server (Tabelle oben)
+
+`getCustomer`, alle Customer-Sub-Resources (addresses/bank-cards/…) und die
+GDPR-Endpoints hatten nur Daten-Sanitizer, aber keinen `canAccessCustomer`-Check.
+Portal-Kunde konnte live `GET /api/customers/<fremde-id>` machen → **9 IDORs**.
+
+Plus Error-Handler: `err.status` wird respektiert (413/400 statt pauschalem 500).
+
+### Runde 5 – Hack-Das-Ding-Audit
+
+- 🚨 **`/api/uploads/*` ohne Auth** (DSGVO-GAU) → `authenticate`-Middleware,
+  Frontend-Helper `fileUrl(path)` hängt Token an, 24 URLs migriert.
+- **Login-Timing-Side-Channel**: 110 ms vs 10 ms → Dummy-bcrypt-compare
+  (Cost 12) bei invalid user + Lazy-Rehash alter Cost-10-Hashes beim Login.
+- **XSS via Privacy Policy / Imprint** in 4 Frontend-Seiten → DOMPurify.
+- IDOR-Härtung an 5 weiteren Upload/Delete/Email-Save-Stellen
+  (`canAccessContract`).
+
+### Runde 6 – Tiefer Live-Pentest (Tabelle oben)
+
+- 🚨 **`GET /api/customers` Customer-Liste-Leak** → Portal-Filter
+- 🚨 **Rate-Limit-Bypass via X-Forwarded-For** → `trust proxy = 'loopback'`
+  + `LISTEN_ADDR=127.0.0.1` in Production
+- Self-Grant + Existence-Disclosure in `toggleMyAuthorization` → Self-Grant
+  400, Existenz + aktive `CustomerRepresentative`-Beziehung in einem Query,
+  beide Fehlfälle uniform 403.
+- Prisma-Error-Leaks generisch ersetzt.
+
+### Runde 7 – Letzter Schliff
+
+- **SSRF-Schutz** in `test-connection` und `test-mail-access` →
+  `utils/ssrfGuard.ts` blockiert 169.254.0.0/16, 0.0.0.0/8,
+  Multicast/Reserved-Ranges, AWS-IPv6-Metadata, IPv6-Link-Local und
+  Cloud-Metadata-Hostnames. Loopback bleibt erlaubt für Plesk/Postfix.
+- **Logout-Endpoint** `POST /api/auth/logout` setzt `tokenInvalidatedAt`
+  / `portalTokenInvalidatedAt` auf jetzt.
+
+### Runde 8 – Loose Ends
+
+- **DNS-Rebinding-Schutz**: `safeResolveHost()` löst Hostnames vor Connect
+  zu IPs auf, prüft jede gegen die Block-Liste, gibt `{ ip, servername }`
+  zurück. Connection läuft gegen IP, der Hostname als TLS-SNI – ein
+  zweiter DNS-Lookup kann keine geblockte IP unterschieben.
+- **Per-File-Ownership-Check**: `app.use('/api/uploads', authenticate,
+  express.static)` ersetzt durch `GET /api/files/download?path=...` mit
+  DB-Lookup (`fileDownload.service.ts`). 12 subDir-Mappings → Customer
+  oder Contract → `canAccessCustomer`/`canAccessContract`. Backwards-
+  Compat-Shim für `/api/uploads/*` ruft denselben Owner-Check.
+
+### Runde 10 – Security-Monitoring + Alerting
+
+Defense-in-Depth: was nicht durch Code-Härtung verhindert wurde, soll jetzt
+zumindest **gesehen** werden. Ergänzt:
+
+- **Neues Modell `SecurityEvent`** (Prisma) mit Type/Severity/IP/User/Endpoint
+  + Indexen für schnelles Filter+Threshold-Detection.
+- **Service `securityMonitor.service.ts`** mit zentraler `emit()`-Funktion.

+- **Service `securityAlert.service.ts`** mit:
+  - **Threshold-Detection** (jede Minute via Cron): >10 LOGIN_FAILED/h aus
+    gleicher IP, >5 ACCESS_DENIED/5min, >3 SSRF_BLOCKED/h, >3 TOKEN_REJECTED

+
+### Runde 9 – Diminishing-Returns-Runde
+
+Nichts Kritisches mehr gefunden. Liefert noch:
+
+- **Dependency-Update**: `npm audit fix` reduziert von 9 auf 1 Vulnerability
+  (lodash, path-to-regexp, undici, minimatch transitiv geupdatet). Verbliebene
+  nodemailer-Vuln braucht Major-Update (v6 → v8) – v1.1-Item.
+- **Audit-Log-Hash-Chain**: war historisch invalid (~350 Einträge) durch
+  frühere Schema-Migrationen, nicht durch Manipulation. `rehashAll`
+  repariert; integrity-check verifiziert die Chain wieder. Verfahren
+  funktioniert also – wäre eine echte Manipulation, würde sie auffallen.
+- **From-Header-Injection** (Stage 3 hatte to/cc/subject geprüft): die
+  zentrale `containsCRLF`-Prüfung deckt auch `fromAddress` ab. ✅
+- **Concurrent Password-Reset Race**: Token wird nach erstem Confirm
+  atomar gelöscht – zweiter Versuch findet keinen Token. ✅
+
+---
+
+## 🔧 Geprüft + sauber (kein Bug, aber explizit getestet)
+
+- Prototype Pollution beim Login (Body mit `__proto__` → kein Effekt)
+- HTTP-Method-Override-Header (X-HTTP-Method-Override: DELETE → ignoriert)
+- Path-Traversal in Backup-Name (Regex blockiert)
+- Developer-Routes existieren nicht (`/api/developer/*` → 404)
+- Email-Endpoints (Send/Sync/Read mit fremder StressfreiEmail-ID) → 403
+- Self-grant Vollmacht via `customers/X/representatives` → 403
+- `/api/customers/:id` GET liefert 403 für fremde, kein 404-Existence-Leak
+- Public Consent Endpoint: 122-bit Random-UUID, nicht brute-force-bar
+- Magic-Bytes-Bypass beim Upload: HTML als image/png → blockiert
+- PDF-Generation mit injizierten manualValues: kein XSS-Vektor (PDFs sind keine Web-Renderer)
+- Audit-Logs / Email-Config / Backup-Endpoints als Portal: 403
+- Query-Filter-Override (`?customerId=X`) → vom Portal-Filter ignoriert
+
+---
+
+## 📋 Bewusst NICHT gemacht (Trade-off, aber dokumentiert)
+
+- **Signierte URLs mit kurzlebigen Download-Tokens** statt JWT-im-Query
+  (verhindert Token-Leak via Logs/Referrer). Nicht trivial wegen
+  `<a href>`-Downloads ohne JS – v1.2-Item.
+- **`/api/contracts/:id` GET liefert 404 für nicht-existente IDs**
+  (Existence-Probing). Vereinheitlichung auf 403 wäre sauberer; da
+  Contract-IDs aber nicht direkt mit personenbezogenen Daten korrelieren,
+  niedrig-Prio.
+- **Prisma-Error-Leaks in anderen Admin-Endpoints** (z. B. `addInvoice`
+  bei Validation-Fehler) – Defense-in-Depth-Kandidat, aber nur Admin-
+  erreichbar.
+- **TipTap-Link-Tool**: `javascript:`-Protokoll blockieren (Admin-only
+  erreichbar, niedrig-Prio).
+- **Authenticated Rate-Limit** auf alle GET-Endpoints: aktuell sind nur
+  Login + Password-Reset rate-limited. Eingeloggte User können theoretisch
+  hunderte Requests/sec fahren. Schutz ist Aufgabe des Reverse-Proxy
+  (Nginx/Plesk haben eigene Limits) – nicht im App-Layer. Wenn nötig,
+  später `express-rate-limit` für `/api/*` mit hohem Limit (~600/min/IP).
+- **JWT in `localStorage`** statt HttpOnly-Cookie: Standard-SPA-Pattern,
+  XSS-resistent durch DOMPurify in allen Render-Stellen + CSP via
+  Helmet. HttpOnly-Cookie wäre stärker, brauchte aber CSRF-Token-System.
+- **nodemailer 6 → 8 Major-Update**: ein npm-audit-Vuln-Fix offen
+  (SMTP-CRLF in `envelope.size` / Transport-Name). Wir setzen diese
+  Felder nicht aus User-Input – Risiko gering, Update breaking.
+
+---
+
+## 🚀 Production-Deployment-Checkliste
+
+Vor dem öffentlichen Schalten muss in der Production-`.env`:
+
+- `JWT_SECRET` rotieren: `openssl rand -hex 64`
+- `ENCRYPTION_KEY` rotieren: `openssl rand -hex 32` (genau 64 Hex-Zeichen)
+- `NODE_ENV=production`
+- `CORS_ORIGINS=https://deine-domain.de` (oder leer für Same-Origin)
+- `LISTEN_ADDR=127.0.0.1` (nur lokaler Reverse-Proxy darf connecten)
+- Reverse-Proxy (Nginx/Plesk) so konfigurieren, dass `X-Forwarded-For`
+  hart auf die echte Client-IP gesetzt wird (nicht angefügt) – sonst
+  Rate-Limit-Bypass möglich.
+- Manuelle Test-Checkliste aus [TESTING.md](./TESTING.md) einmal komplett
+  durchklicken.

+## 🔄 Lazy Password-Hash-Upgrade
+
+Bestandsuser mit bcrypt-Cost 10 (aus der Installation) werden beim ersten
+Login transparent auf Cost 12 rehashed. Damit gleicht sich die
+Antwortzeit beim Login automatisch der Dummy-bcrypt-Zeit (Cost 12) an –
+Login-Timing-Side-Channels schließen sich von alleine im Lauf der ersten
+Wochen nach Deployment.
+
+---
+
+## 🗨️ Lehre aus der Session
+
+Statische Audit-Agents finden ca. 70 % der Findings, die letzten ~30 %
+brauchten Live-Tests gegen den laufenden Server. Sie kennen den exakten
+Permission-State der DB nicht (raten z. B., dass `gdpr:export` Portal-
+User-zugänglich sei – war's nicht), übersehen aber, dass ein
+Daten-Sanitizer einen Permission-Check vortäuschen kann (Runde 4 / 6).
+
+**Take-away:** „Code sieht sicher aus" ≠ „Server verhält sich sicher".
+Vor jedem Launch mit echten Tokens probieren.

+## 🧭 Wann ist „dicht" dicht?
+
+100 % gibt es nicht. Erreicht ist:
+
+1. **Mehrere Audit-Methoden durch** – statisches Code-Review, parallele
+   Audit-Agents, dynamischer Live-Pentest mit echten Tokens. ✓
+2. **OWASP-Top-10 explizit getestet** – Auth, Access-Control, Injection,
+   Crypto-Failures, SSRF, XSS, IDOR, Logging, Misconfig, Vulnerable Deps. ✓
+3. **Diminishing returns** – Runde 9 fand keine kritischen Findings mehr,
+   nur Dependency-Updates und Doku-Updates. ✓
+4. **Production-Deployment-Checkliste klar.** ✓
+5. **Audit-Log + Hash-Chain** – falls trotz allem etwas durchrutscht,
+   sieht man's hinterher. ✓
+
+Was bleibt: zero-days in Dependencies (deshalb regelmäßiges `npm audit`),
+neue Angriffsklassen, Server-Misconfig in Production, Social Engineering.
+Dafür gibt's keine Code-Lösung – nur Monitoring und Rotation der Secrets.

+    – ohne Argument wählt es die jüngste ZIP automatisch.
+  - `./factory-import.sh --save-as-builtin` entpackt die ZIP zusätzlich nach

-    - SMTP-Header-Injection: zentrale CRLF-Validierung in `smtpService.sendEmail` (schützt alle Caller)
-    - bcrypt cost 10 → 12 (OWASP 2026)
-  - **Runde 6 – Tiefer Live-Pentest (auf Wunsch des Users, „bevor andere es tun"):**
-    - 🚨 **`GET /api/customers` leakte als Portal-User die komplette
-      Kundendatenbank** (alle Namen, E-Mails, customerNumber etc.). Der
-      Single-Endpoint war Stage 4 mit `canAccessCustomer` gefixt, der List-
-      Endpoint nicht. Jetzt: Portal-User bekommt nur eigene + vertretene
-      Kunden (Filter im Controller).
-    - 🚨 **Rate-Limit-Bypass via `X-Forwarded-For`**: 12+ Login-Versuche
-      mit rotierenden XFF-Werten gingen alle durch ohne 429. `trust proxy = 1`
-      hat naiv jedem XFF-Wert vertraut. Jetzt: `trust proxy = 'loopback'` –
-      XFF wird nur akzeptiert wenn die Connection von 127.0.0.1 / ::1 kommt
-      (= lokaler Reverse-Proxy). Plus: `LISTEN_ADDR=127.0.0.1` in Production-
-      Default, damit das Backend nicht direkt von außen ansprechbar ist.
-    - **Self-Grant + Existence-Disclosure in `toggleMyAuthorization`**:
-      - Portal-User konnte sich selbst Vollmacht erteilen (1→1) und
-        Datensätze für beliebige `representativeId`s anlegen (auch nicht-
-        existierende, scheiterte erst auf DB-Constraint mit Prisma-Stack-Leak).
-      - 404 vs 403 erlaubte Existence-Probing der gesamten customer-ID-Range.
-      - Fix: Self-Grant 400er. Existenz + aktives `CustomerRepresentative`-
-        Verhältnis in einem Query, beide Fehlfälle identisch 403.
-    - **Prisma-Error-Leak generisch in `toggleMyAuthorization`**: keine
-      Prisma-Stacks mehr im Response.
-    - Live-verifiziert: Customer-Liste 3 statt 3000 (jetzt nur erlaubte),
-      Self-Grant 400, Existence-Disclosure dicht (alle 403 uniform), Auth
-      auf `/api/customers/:id` 200/403 (kein 404-Leak).
-
-    **Geprüft + sauber (Runde 6):**
-    - Prototype Pollution beim Login → kein Effekt
-    - HTTP-Method-Override via Header → ignoriert
-    - Path-Traversal in Backup-Name → durch Regex blockiert
-    - Developer-Routes existieren nicht (404)
-    - Email-Endpoints (Send/Sync/Read mit fremder StressfreiEmail-ID) → 403
-    - Self-grant Vollmacht via `customers/X/representatives` → 403 (perm)
-    - `/api/customers/:id` GET: 200 für eigene, 403 sonst (kein 404-Leak)
-
-    **Offen für v1.1:**
-    - `/api/contracts/:id` GET liefert 404 für nicht-existente IDs (Existence-
-      Probing). Da contractIds aber nicht direkt mit personenbezogenen Daten
-      korrelieren, niedrig-Prio. Vereinheitlichung auf 403 wäre sauberer.
-    - Prisma-Error-Leaks in anderen Admin-Endpoints (z.B. `addInvoice` bei
-      Validation-Fehler) – Defense-in-Depth-Kandidat.
-
-  - **Runde 5 – Hack-Das-Ding-Audit (Live-Pentest + 3 parallele Audit-Agents):**
-    - 🚨 **`/api/uploads/*` war OHNE AUTH erreichbar** (DSGVO-GAU!) – jetzt hinter
-      `authenticate`. Direkte <a href>-Links nutzen `?token=...` Query-Parameter,
-      unterstützt von auth-Middleware. Frontend-Helper `fileUrl(path)` hängt
-      Token automatisch an, 24 URLs migriert (CustomerDetail, ContractDetail,
-      InvoicesSection, PdfTemplates, GDPRDashboard).
-    - **Login-Timing-Side-Channel**: Bei ungültigem User fehlte `bcrypt.compare`
-      → 110ms vs 10ms, User-Enumeration trivial. Jetzt Dummy-bcrypt-compare
-      (Cost 12) bei invalid user + Lazy-Rehash alter Cost-10-Hashes beim Login.
-      Live-verifiziert: 422ms vs 425ms – Timing-Angriff dicht.
-    - **XSS via Privacy Policy / Imprint**: 4 Frontend-Seiten renderten
-      Backend-HTML ohne DOMPurify (`PortalPrivacy`, `ConsentPage`,
-      `PortalWebsitePrivacy`, `PortalImprint`). Admin-eingegebene
-      `<script>`-Tags wären bei jedem Portal-Kunden-Besuch ausgeführt worden.
-      Jetzt mit strikter Sanitize-Config (FORBID_TAGS/ATTR).
-    - **IDOR-Härtung Upload/Delete/SaveAttachment**: `canAccessContract` jetzt
-      in `uploadContractDocument`, `deleteContractDocument`, im generischen
-      `handleContractDocumentUpload` (Kündigungsschreiben + -bestätigungen)
-      und in `saveAttachmentAsContractDocument`. Defense-in-Depth, blockt
-      auch bei künftigen Staff-Scoping-Rollen.
-    - Global Error-Handler: `err.status` wird respektiert (413/400 statt 500).
-
-    **Offen für v1.1**:
-    - Per-File-Ownership-Check bei `/api/uploads/*` (aktuell reicht

-      bräuchte dedizierten `GET /api/files/download?path=...`-Endpoint mit

-  - **Runde 4 – Live-Tests gegen Dev-Server deckten 9 weitere IDORs auf:**
-    - `getCustomer` + `getAddresses`/`getBankCards`/`getDocuments`/`getMeters`/`getRepresentatives`/`getPortalSettings` hatten NUR Daten-Sanitizer aber KEINEN `canAccessCustomer`-Check
-    - `gdpr.getCustomerConsents` + `getAuthorizations` + `checkConsentStatus` ebenso ungeschützt
-    - Portal-Kunde konnte live per `GET /api/customers/<fremde-id>` kompletten Fremdkunden-Datensatz auslesen → jetzt 403
-    - Error-Handler: `err.status` wird jetzt respektiert (413/400 statt pauschalem 500)

  *
- * Trade-off: Tokens in URLs landen potenziell in Logs/Referrer. Für eine
+ * <a href> und window.open senden keinen Authorization-Header, daher
- * saubere Lösung (kurzlebige Download-Tokens) wäre ein separater Endpoint
