CVE-2026-33759: AVideo: Unauthenticated IDOR in playlistsVideos.json.php Exposes Private Playlist Contents

March 26, 2026 (updated March 27, 2026)

The objects/playlistsVideos.json.php endpoint returns the full video contents of any playlist by ID without any authentication or authorization check. Private playlists (including watch_later and favorite types) are correctly hidden from listing endpoints via playlistsFromUser.json.php, but their contents are directly accessible through this endpoint by providing the sequential integer playlists_id parameter.
