Technical details

A stored XSS vulnerability exists in the videoDownloadedLink parameter processed by objects/aVideoEncoder.json.php. The unescaped value is rendered as a Source tag attribute in view/managerVideos_body.php, allowing event-handler payloads to execute in administrator browsers. An authenticated uploader with video upload privileges can inject the payload; execution occurs when an administrator manages videos.
