Frigate is an open source network video recorder. Prior to 0.17.2, the WebSocket handler in frigate/comms/ws.py forwards attacker-selected message topics to the dispatcher without checking the authenticated user's role because the nginx authentication subrequest does not provide role-aware authorization to the handler. Any authenticated viewer can send admin-only topics such as restart, notifications/set, and camera detection, recording, snapshot, audio, motion, and enablement settings, causing service restarts or disabling security monitoring functions.
Authentication must be enabled and valid viewer credentials are required. This issue is fixed in version 0.17.2.
