CVE-2026-33499
PHP vulnerability analysis and mitigation

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the view/forbiddenPage.php and view/warningPage.php templates reflect the $_REQUEST['unlockPassword'] parameter directly into an HTML <input> tag's attributes without any output encoding or sanitization. An attacker can craft a URL that breaks out of the value attribute and injects arbitrary HTML attributes including JavaScript event handlers, achieving reflected XSS against any visitor who clicks the link. Commit f154167251c9cf183ce09cd018d07e9352310457 contains a patch.
