Summary
mH-DEVELOPER smart home module does not verify tokens in its authorization middleware, leaving all HTTP API and WebSocket endpoints accessible without authentication. An unauthenticated attacker on the LAN can query these endpoints, access system information, and send raw control commands to manipulate building automation devices. This issue was fixed in version 3.0.30
