Updated Sep 10, 2026
Nginx
Parameter Value
CVSS 8.7 (HIGH)
Type CWE-200 (Information Exposure)
Vendor Nginx
Public PoC No

AVideo through revision c3edcc274c389816d434acadac07ee78eaf330c1 (master, 2026-08-23) does not enforce the Live stream password check on the stats endpoint or on the HLS origin. Live::_getStats() (plugin/Live/Live.php) returns a password-protected transmission's RTMP stream key, its isPasswordProtected flag, and its HLS (m3u8) URL to unauthenticated callers, in both the public applications list and the hidden_applications branch used when canSeeLiveFromLiveKey() fails. Separately, the shipped NGINX configuration (deploy/nginx/nginx.conf) serves the .m3u8 playlist, the AES-128 key, and the transport-stream segments from the /live location without any auth_request (the auth_key_check directive in the .key location is commented out).

A remote, unauthenticated attacker can therefore retrieve the stream key and decryption key and watch a password-protected live transmission without supplying the configured password. No patched version was available at the time of the advisory.
