Arbitrary File Deletion via Path Traversal in WWBN AVideo CloneSite
CVE-2026-33293 is a path traversal vulnerability in WWBN AVideo, an open source video platform, affecting versions prior to 26.0. The flaw is in plugin/CloneSite/cloneServer.json.php, where the deleteDump parameter is passed directly to unlink() without path sanitization or restriction to an intended directory. An attacker with valid clone credentials can supply traversal sequences such as ../../ to escape the expected path and cause deletion of arbitrary files on the server. The issue can be used to remove critical application files, including configuration.php, resulting in service failure and potentially weakening application security controls.

Impact
What an attacker gets, and what they’ve been doing with it.
Mitigation
If you can’t patch tonight, do this now.
plugin/CloneSite/cloneServer.json.php to only trusted administrative workflows. Rotate or revoke clone credentials that are not strictly necessary. Apply server-side validation to reject traversal sequences and enforce canonical-path checks before any file deletion operation. Limit filesystem permissions of the web application user so it cannot delete sensitive application or system files outside the minimum required directories. Monitor for suspicious requests containing traversal patterns such as ../ targeting CloneSite endpoints.Remediation
Patch, then assume compromise.
deleteDump parameter. The fix should ensure the supplied path cannot traverse outside the intended directory and that file deletion is restricted to explicitly allowed files or locations. Review the referenced fix commit and security advisory, and verify that all deployed instances, including any customized forks, incorporate the patch.Exploits
