Live-history mutation via tokenless GET requests
Published Sep 8, 2026 · Updated Sep 8, 2026
Cross-site request forgery in WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 allows remote attackers to alter live-stream history. The deleteHistory.json.php and finishAll.json.php handlers accept state-changing GET requests without validating a CSRF token. Exploitation requires an administrator with an active session to visit an attacker-controlled page; the requests then delete all live transmission history or mark streams as finished.
