CVE-2026-90538WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a missing authorization vulnerability in playlistsFromUser.json.php that allows unauthenticated attackers to read private playlists by requesting another user's identifier. Attackers can retrieve Favorite and Watch Later playlists belonging to other users due to improper cache keying that conflates requests across different user contexts.
