Vulnerability Title
AVideo Affected by Arbitrary File Deletion via Path Traversal in CloneSite deleteDump Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
WWBN AVideo is an open source video platform. Prior to version 26.0, the `deleteDump` parameter in `plugin/CloneSite/cloneServer.json.php` is passed directly to `unlink()` without any path sanitization. An attacker with valid clone credentials can use path traversal sequences (e.g., `../../`) to delete arbitrary files on the server, including critical application files such as `configuration.php`, causing complete denial of service or enabling further attacks by removing security-critical files. Version 26.0 fixes the issue.
