CVE-2026-67827Public exploitNetwork attack vector

Authenticated command execution via ffmpeg.snap template overwrite

Published Sep 21, 2026 · Updated Sep 21, 2026

OS command injection in ZLMediaKit allows remote authenticated users to execute commands through the HTTP API as the server process. The setServerConfig handler stores an attacker-controlled ffmpeg.snap template without validation, and getSnap passes the resulting command to Process::run(). Access requires the API secret; older deployments using the historical default secret expose command execution with the ZLMediaKit process privileges.
