Information disclosure in Wwbn Avideo
CVE-2026-89248
AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 is missing an authentication/authorization check in plugin/WebRTC/status.json.php. When the WebRTC plugin is present, any unauthenticated remote user can request /plugin/WebRTC/status.json.php and receive JSON containing the absolute filesystem path of the WebRTC2RTMP helper binary (revealing the document-root path), the configured WebRTC port, file_exists/is_executable status for the binary, the contents of the WebRTC log/JSON files (videos/WebRTC2RTMP.log) when present, and whether the configured port is reachable on loopback (127.0.0.1) and on the public address. The endpoint performs no User::isLogged(), User::isAdmin(), or forbiddenPage() check. The issue was unfixed at the time of reporting.
