Vulnerability details
The vulnerability allows a remote attacker to create, overwrite, or delete categories, disrupt category availability, and trigger installed plugins' updateScript() methods in an administrator's session.
The vulnerability exists due to missing cross-site request forgery protection in AVideo's objects/categoryAddNew.json.php, objects/categoryDelete.json.php, and objects/pluginRunUpdateScript.json.php endpoints when processing state-changing POST requests. A remote attacker can lure a logged-in administrator to a malicious page that submits forged forms to modify categories or invoke plugin update scripts without authorization.
