Technical details
Stored XSS in the video trailer1 field rendered unsanitized in an inline onclick JavaScript attribute. The isValidURL() validator rejects literal quote and bracket characters but allows HTML entity sequences (e.g., '), which the browser decodes when parsing the attribute, breaking out of the JavaScript string. Any authenticated user with video upload permissions can inject a payload such as http://a/');alert(document.domain);// to execute arbitrary JavaScript in any visitor's session.
