Description

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the YPTWallet Stripe payment confirmation page directly echoes the `$_REQUEST['plugin']` parameter into a JavaScript block without any encoding or sanitization. The `plugin` parameter is not included in any of the framework's input filter lists defined in `security.php`, so it passes through completely raw. An attacker can inject arbitrary JavaScript by crafting a malicious URL and sending it to a victim user. The same script block also outputs the current user's username and password hash via `User::getUserName()` and `User::getUserPass()`, meaning a successful XSS exploitation can immediately exfiltrate these credentials. Commit fa0bc102493a15d79fe03f86c07ab7ca1b5b63e2 fixes the issue.
