WWBN AVideo 29.1.0 through 29.7.1 contains a stored cross-site scripting vulnerability that allows registered users to inject markup through the channel About field rendered in feed/index.php. Attackers can store an unquoted event-handler payload that bypasses feedHtmlDescription() filtering and executes via rss-style.xsl for any visitor, including administrators, viewing the channel feed.
