## 2. Security Assessment

### 2.1 Critical Security Issues

**Status:** 🔴 **CRITICAL CONCERNS**

#### Issue 1: Build Error Suppression
```javascript
// next.config.mjs
eslint: {
  ignoreDuringBuilds: true,  // ❌ DANGEROUS
},
typescript: {
  ignoreBuildErrors: true,   // ❌ DANGEROUS
}
```

**Risk:** Type errors and linting issues can introduce runtime bugs in production.

**Impact:** HIGH - Could lead to production failures

**Recommendation:**
- [ ] **MUST FIX:** Remove error suppression, fix all TypeScript/ESLint errors
- [ ] Set up pre-commit hooks to prevent errors from reaching production
- [ ] Use CI/CD to block deployments with errors

#### Issue 2: Security Incident History
- Previous backdoor vulnerability (CVE-2025-66478) in Next.js 15.3.1
- **Status:** ✅ Resolved (upgraded to Next.js 16.1.1)
- **Action Required:** Security audit of all configuration files

**Recommendations:**
- [ ] Complete security audit of all config files
- [ ] Review all dynamic imports
- [ ] Implement file integrity monitoring
- [ ] Set up automated security scanning (Snyk, npm audit)

#### Issue 3: Missing Rate Limiting
**Status:** 🔴 **CRITICAL**

No rate limiting found on API endpoints. This exposes the application to:
- DDoS attacks
- Brute force attacks
- Resource exhaustion

**Recommendations:**
- [ ] Implement rate limiting middleware (e.g., `@upstash/ratelimit`)
- [ ] Configure per-endpoint limits
- [ ] Add IP-based throttling
- [ ] Set up Redis-based distributed rate limiting

#### Issue 4: Environment Variable Validation
**Status:** ⚠️ **PARTIAL**

**Current State:**
- ✅ Basic validation in `lib/env.ts` using Zod
- ❌ Many critical variables not validated (N8N_API_KEY, S3 credentials, etc.)

**Missing Validations:**
- `N8N_API_KEY` (required but not in schema)
- `MINIO_ACCESS_KEY`, `MINIO_SECRET_KEY`
- `S3_BUCKET`
- `NEXTAUTH_SECRET` (should be validated for strength)

**Recommendations:**
- [ ] Expand `env.ts` schema to include ALL environment variables
- [ ] Add validation for secret strength (NEXTAUTH_SECRET min length)
- [ ] Fail fast on missing critical variables at startup

### 2.2 Authentication & Authorization

**Status:** ✅ **Good**

- ✅ NextAuth.js with Keycloak provider
- ✅ JWT-based sessions (4-hour timeout)
- ✅ Role-based access control
- ✅ Session refresh mechanism

**Concerns:**
- ⚠️ Some API routes have inconsistent auth checks
- ⚠️ No API key rotation strategy documented

**Recommendations:**
- [ ] Standardize auth middleware across all API routes
- [ ] Implement API key rotation for N8N integration
- [ ] Add audit logging for authentication events

### 2.3 Data Security

**Status:** ⚠️ **Needs Review**

**Database:**
- ✅ Passwords stored (assumed hashed, need verification)
- ⚠️ No encryption at rest mentioned
- ⚠️ Connection strings in environment (should use secrets manager)

**File Storage:**
- ✅ S3-compatible storage
- ⚠️ No file size limits enforced
- ⚠️ No virus scanning mentioned

**Recommendations:**
- [ ] Verify password hashing implementation (bcrypt with proper salt rounds)
- [ ] Implement file upload size limits
- [ ] Add file type validation
- [ ] Consider encryption at rest for sensitive data
