What is CVE-2026-82932?

The mH-DEVELOPER smart home module has a critical flaw where it fails to load necessary firewall rules upon startup. As a result, all services such as SSH, HTTP, WebSocket, and Node-RED are exposed on the local area network without any access control measures. This oversight allows any client within the same network to access these services without restrictions, increasing the risk of unauthorized access and potential exploitation.

Affected Version(s)

mH-DEVELOPER 0 < 3.0.30
