CRITICAL FIXES:
- Fixed SQL injection vulnerability in document deletion endpoint
- Changed PostgreSQL-style (%s) to SQLite-style (?) placeholders
- Updated JSON operator from metadata->>'filename' to json_extract()
- Affected lines: server.py:666, 679
- Fixed CORS security risk (allow_origins=["*"])
- Restricted to configurable whitelist via ALLOWED_ORIGINS env var
- Default: localhost:5173,8051 for development
- Production: Set to specific domains only
- Added rate limiting to prevent DoS attacks
- Implemented slowapi for per-IP rate limiting
- Chat endpoint: 20 requests/minute per IP
- Prevents resource exhaustion
Security impact: CRITICAL → SECURE
Files: mcp_server/server.py, .env.example
Implemented optional authentication to keep strangers out of the
Claude OS frontend when deployed to production servers.
Backend (FastAPI):
- mcp_server/auth.py: JWT-based authentication
* Bcrypt password hashing
* Environment-based user credentials (no database needed)
* 7-day token expiration
* Optional - disabled by default
- mcp_server/server.py: Auth endpoints
* POST /api/auth/login - Returns JWT token
* GET /api/auth/me - Get current user
* GET /api/auth/status - Check if auth enabled
- requirements.txt: Added dependencies
* passlib[bcrypt] for password hashing
* python-jose[cryptography] for JWT
* python-multipart for form data
Frontend (React):
- frontend/src/lib/auth.tsx: Auth context and hooks
* Manages authentication state
* Automatic token validation
* localStorage for token persistence
- frontend/src/pages/Login.tsx: Beautiful login page
* Gradient design matching Claude OS branding
* Clear error messages
* Loading states
- frontend/src/components/ProtectedRoute.tsx: Route protection
* Automatically redirects to login if not authenticated
* Shows loading state during auth check
* Bypasses auth if disabled
- frontend/src/App.tsx: Integrated auth
* Wrapped app in AuthProvider
* Protected routes for Welcome and MainApp
* Login route for authentication
Documentation:
- AUTH_SETUP.md: Complete authentication guide
* Quick start instructions
* Password hash generation
* Production deployment steps
* Troubleshooting guide
- .env.example: Added auth configuration
* CLAUDE_OS_EMAIL (login email)
* CLAUDE_OS_PASSWORD (dev - plain text)
* CLAUDE_OS_PASSWORD_HASH (production - bcrypt hash)
* CLAUDE_OS_SECRET_KEY (JWT secret)
- docs/PRODUCTION_DEPLOYMENT.md: Added Step 5
* Authentication setup for production
* Hash and secret generation commands
* Testing instructions
Features:
✅ Optional authentication (disabled by default)
✅ Single user via environment variables
✅ Secure bcrypt hashing
✅ JWT tokens with 7-day expiration
✅ Beautiful login UI
✅ No database required for user management
Usage:
1. Set CLAUDE_OS_EMAIL and CLAUDE_OS_PASSWORD in .env
2. Restart Claude OS
3. Visit /login to authenticate
4. Token valid for 7 days
To disable auth: Remove CLAUDE_OS_EMAIL from .env
