Vulnerability Title
WWBN AVideo Vulnerable to stored XSS via Unanchored Duration Regex in Video Encoder Receiver
Source: NVD (National Vulnerability Database)
Vulnerability Description
WWBN AVideo is an open source video platform. In versions 29.0 and below, the `isValidDuration()` regex at `objects/video.php:918` uses `/^[0-9]{1,2}:[0-9]{1,2}:[0-9]{1,2}/` without a `$` end anchor, allowing arbitrary HTML/JavaScript to be appended after a valid duration prefix. The crafted duration is stored in the database and rendered without HTML escaping via `echo Video::getCleanDuration()` on trending pages, playlist pages, and video gallery thumbnails, resulting in stored cross-site scripting. Commit bcba324644df8b4ed1f891462455f1cd26822a45 contains a fix.
