Vulnerability Title
AVideo-Encoder vulnerable to stored DOM cross-site scripting through queue titles
Source: CVE Program / CVE List V5
Vulnerability Description
AVideo is a video-sharing Platform. Prior to 8.1.0, `view/queue.php` uses `pathinfo` on the caller-controlled `fileURI` and stores its filename through `setTitle` in `encoder_queue.title` without neutralization. `fileURI` is not in the `objects/security.php` filter lists, and the `Login::canUpload()` capability needed to submit a queue entry can be self-granted using an attacker-controlled login site without legitimate encoder credentials. `view/index.php` loads `queue.json` from `view/queue.json.php` into the `#grid` jQuery Bootgrid table; its title formatter concatenates `row.title` into raw cell HTML. An attacker can therefore store an HTML title whose event handler runs in a privileged viewer's browser. `Encoder::getAll` limits nonadministrators to their own streamer's rows, so the victim must be an administrator who sees all rows or an operator on the attacker's streamer. A second `.html()` sink in the progress panel uses the same title but additionally depends on a helper script loaded from the streamer; the Bootgrid sink is reachable from encoder code alone. The script can read session-visible data and rendered streamer credentials, act with the viewer's privileges, and execute again for each qualifying viewer until the row is removed. This issue is fixed in version 8.1.0.
