AVideo contains a stored cross-site scripting vulnerability in the video trailer1 field rendered unsanitized within an inline onclick JavaScript string. Attackers with video upload permission can store HTML entity-encoded payloads that bypass isValidURL() validation and are decoded by the browser to break out of the JavaScript string, executing arbitrary code in any visitor's session including administrators.
