AVideo through revision c3edcc274c389816d434acadac07ee78eaf330c1 contains a missing authorization vulnerability in plugin/PlayerSkins/seo.php that allows unauthenticated attackers to access password-protected video sources by calling getSources() without password validation. Attackers can request the seo.php endpoint with a video ID to obtain the direct MP4 URL and read protected media bytes without supplying the configured password.
AnalysisAI
Password-protection bypass in WWBN AVideo's PlayerSkins SEO plugin endpoint allows unauthenticated remote attackers to retrieve direct MP4 URLs for videos that owners have restricted behind passwords. The flaw resides in plugin/PlayerSkins/seo.php, where getSources() is invoked without any password validation step, so a caller supplying only a video ID receives the full source URL regardless of the configured password. …
