NO FIX YET · SEE WHAT TO DO
AVideo versions 14.3 through 29.7.1 store the videoDownloadedLink value without escaping, so an uploader can plant event-handler script in a URL. When an administrator opens the video manager page, the script runs in their session and can be used to install a PHP plugin archive.
