DescriptionCVE.org

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a cross-site request forgery vulnerability in playlistRemove.php that allows attackers to delete playlists by skipping CSRF protection checks. Attackers can craft a malicious form that submits a POST request to playlistRemove.php, causing a victim's playlist to be deleted when they visit the attacker's page while logged in.

AnalysisAI

Cross-site request forgery in WWBN AVideo's playlistRemove.php endpoint allows remote attackers to silently delete authenticated users' playlists by luring victims to a malicious webpage. The endpoint processes POST requests for playlist deletion without validating a CSRF token, meaning any browser-initiated request carrying a valid session cookie - regardless of origin - is accepted. …
