Authenticated file deletion via unchecked stored path
Published Sep 4, 2026 · Updated Sep 4, 2026
Arbitrary file deletion in CRMEB 6.0.0 allows remote authenticated users to delete PHP-accessible files through an admin API request. The videoDataSave() flow stores a client-controlled video_path without canonicalization or upload-root containment, and local deletion later passes it to unlink(). Administrator authentication with file-management permission and local storage are required; impact is limited to files removable by the PHP process.
