## Description

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a cross-site request forgery vulnerability in deleteHistory.json.php and finishAll.json.php that allows unauthenticated attackers to mutate live history by making GET requests without CSRF token validation. Attackers can craft malicious pages that trigger administrator browsers to delete all live transmission history or mark streams as finished when an admin visits the attacker-controlled site.
