CVE-2025-61765

CVE-2025-61765 affects the Python Socket.IO implementation (python-socketio) used for real-time client/server communications. The root cause is unsafe deserialization of messages via Python’s pickle.loads() when inter-server messaging uses a backend message queue (e.g., Redis). In multi-server de...
