Vulnerability from fkie_nvd - Published: 2026-09-11 12:16 - Updated: 2026-09-11 15:21
Severity
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Summary
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.
