Prior to version 26.0, WWBN/AVideo contains a stored cross-site scripting vulnerability in the CDN plugin's download buttons component. The `clean_title` field of a video record is interpolated directly into a JavaScript string literal without any escaping, allowing an attacker who can create or modify a video to inject arbitrary JavaScript that executes in the browser of any user who visits the affected download page.
