Description
wpForo Forum 2.4.14 contains a stored cross-site scripting vulnerability that allows administrators to inject persistent JavaScript via forum description fields echoed without output escaping across multiple theme template files. On multisite installations or with a compromised admin account, attackers set a forum description containing HTML event handlers that execute when any user views the forum listing.
