Summary

xiaozhi-esp32-server through 0.9.8 contains an authentication bypass in WebSocketServer._handle_auth that allows remote unauthenticated attackers to skip Bearer HMAC token verification by spoofing the Device-ID header. An attacker supplying 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.

Risk Assessment

An unauthenticated attacker can hijack a device session, issue voice commands and access conversation context, severely compromising confidentiality and device control.

Recommendation

Upgrade xiaozhi-esp32-server to a version later than 0.9.8 and ensure HMAC token verification cannot be bypassed via the Device-ID header.

Other vulnerabilities in xiaozhi-esp32-server

CVE-2026-116017Medium
Xiaozhi-esp32-server before 0.9.8 contains an insecure direct object reference vulnerability in the manager-api DeviceController.getAddressBook handler that allows authenticated users to read other users' device address books. Attackers with a normal or self-registered account can request /device/address-book/{macAddress} with another user's device MAC to obtain contact MACs, aliases, call permissions, and owner user IDs.
