INPAYX

Critical hardcoded secret keys are present in multiple authentication and API components (e.g., ai/api/server.py uses 'your-secret-key-for-jwt-encryption' as a fallback, backend/api/handlers/user.go and backend/api/models/user.go use 'your-secure-secret-key-here', backend/websocket/server.go uses 'valid-token'). These hardcoded secrets make the system highly vulnerable to unauthorized access and data breaches if environment variables are not correctly set. The WebSocket server also has an open CORS policy (`CheckOrigin: true`) and a basic hardcoded token for authentication, posing significant network security risks. While there are good practices for robust logging, monitoring, and dependency management (GitHub Actions workflows), these are severely undermined by the fundamental secret management issues. Model upload functionality (`ai/api/endpoints.py`) lacks explicit deep content validation, which could allow malicious model payloads.
