CVE-2026-82930

Unauthenticated device control via unchecked API tokens

Published Sep 28, 2026 · Updated Sep 28, 2026

Authentication bypass in F&F Filipowski mH-DEVELOPER before 3.0.30 allows remote attackers on the LAN to control automation via HTTP. Its authorization middleware does not verify tokens, leaving HTTP API and WebSocket endpoints accessible without authentication. LAN access is required; exposed endpoints disclose system information and accept raw commands that manipulate connected building devices.
