CVE-2026-33499

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.
