Multiple critical security risks were identified, primarily revolving around hardcoded secrets and overly permissive network configurations. Several Go backend files (`backend/api/middleware/auth.go`, `backend/api/handlers/user.go`, `backend/api/models/user.go`) contain hardcoded JWT secret keys (`your-secure-secret-key-here`, `your_secret_key`) that are used for authentication token generation and validation. The WebSocket server (`backend/websocket/server.go`) uses a hardcoded token (`valid-token`) for authentication and allows all origins (`CheckOrigin: func(r *http.Request) bool { return true }`), which is highly insecure for production. Similarly, the main Go API server (`backend/api/main.go`) has broad CORS enabled (`corsConfig.AllowAllOrigins = true`). The Python AI server (`ai/api/server.py`) also includes a hardcoded default JWT secret key if `SECRET_KEY` environment variable is not set. These issues make the system unsafe for deployment in a public or production environment without extensive remediation.
