CVE-2026-35450Public exploitNetwork attack vector

Unauthenticated encoding-architecture disclosure via status endpoint

Published Apr 6, 2026 · Updated Apr 6, 2026

Missing authentication in WWBN AVideo 26.0 and earlier allows remote attackers to disclose FFmpeg server connectivity status. The plugin/API/check.ffmpeg.json.php endpoint calls testFFMPEGRemote() and JSON-encodes its result without checking User::isAdmin(), User::isLogged(), or any other access control. Any network client that can reach the endpoint can learn whether standalone FFmpeg is configured and reachable, revealing encoding architecture without altering it.
