Technical details

A stored cross-site scripting (XSS) vulnerability exists in the fv_player_videos[_fv_player_user_video][] parameter due to insufficient input sanitization and output escaping. The vulnerability requires an authenticated subscriber-level user (or above) and depends on an administrator enabling the "Allow visitors to upload videos to their profile" setting. The injected script is stored and executed whenever any user accesses a page containing the malicious profile video.
