CVE-2026-71265Hinoki check available

Worker-thread stack corruption via unbounded RFSEC copy

Published Aug 5, 2026 · Updated Aug 5, 2026

Stack-based buffer overflow in Domoticz allows remote attackers to corrupt its worker-thread stack via crafted MOCHAD_RFSEC input. The MochadTCP::MatchLine handler copies network-received text from m_mochadbuffer into the 50-byte tempRFSECbuf with unbounded strcpy calls in three device-type branches. Reachability requires an unauthenticated path to the configured Mochad TCP bridge on the local network; code execution has not been demonstrated.
