CVE-2026-33293
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.
