Summary

xiaozhi-esp32-server through 0.9.8 is affected. The WebSocketServer._handle_auth function skips Bearer HMAC token verification when a request spoofs the Device-ID header (CWE-290). A remote unauthenticated attacker who supplies an allowlisted MAC-address-shaped device identifier can open an authenticated WebSocket session, issue voice-assistant commands, exchange audio, and read that device's conversation context. CISA SSVC lists exploitation as proof of concept.
