CVE-2026-82930: CWE-306 Missing Authentication for Critical Function in F&F Filipowski mH-DEVELOPER
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
AI Analysis
Technical Summary
CVE-2026-82930 is a missing authentication vulnerability (CWE-306) in the mH-DEVELOPER smart home module by F&F Filipowski. The authorization middleware fails to verify tokens, leaving all HTTP API and WebSocket endpoints accessible without authentication. This enables an unauthenticated attacker on the LAN to access system information and control building automation devices by sending raw commands. The issue was resolved in version 3.0.30.
Potential Impact
An unauthenticated attacker on the local network can access sensitive system information and manipulate building automation devices by sending unauthorized commands. This compromises the confidentiality and integrity of the smart home system. The CVSS 4.0 base score is 6.4 (medium severity), reflecting the network attack vector with no privileges or user interaction required, but with limited scope and impact.
Mitigation Recommendations
Upgrade to mH-DEVELOPER version 3.0.30 or later, where the missing authentication issue has been fixed. No other mitigation is required as the vulnerability is resolved by this official fix.
