Detailed vulnerability description
The vulnerability allows a remote user to execute arbitrary JavaScript in the browser of another user.
The vulnerability exists due to cross-site scripting in the CDN plugin downloadButtons.php component when rendering the user-supplied clean_title field into a JavaScript string literal on the download page. A remote user can create or modify a video with a specially crafted title to execute arbitrary JavaScript in the browser of another user.
