Official description
mH-DEVELOPER smart home module does not load any firewall rules at startup. This leaves all listening services, including SSH, HTTP, WebSocket, and Node-RED, fully exposed on the LAN without access control. Any client on the same network can reach every service. This issue was fixed in version 3.0.30
