CVE-2026-33293Public exploitNetwork attack vector

Authenticated file deletion via unsanitized deleteDump path

Published Mar 22, 2026 · Updated Mar 22, 2026

Path traversal in AVideo before 26.0 allows remote authenticated users to delete arbitrary server files through a CloneSite request. In plugin/CloneSite/cloneServer.json.php, the deleteDump value is appended to the clones directory and passed to unlink() without path validation. A valid approved-clone URL and key are required; deletion can remove application data or configuration.php, causing data loss or a site-wide service interruption.
