 "title": "Media Library Folders <= 8.4.3 - Authenticated (Author+) Insecure Direct Object Reference to Arbitrary Attachment Move/Copy",
 "description": "The Media Library Folders plugin for WordPress is vulnerable to Insecure Direct Object Reference via the mlfp_process_mc_data AJAX action (move_copy_file function) in all versions up to, and including, 8.4.3, due to missing validation that the current user owns the attachments named in the user-controlled 'serial_copy_ids' key and missing validation of the destination 'folder_id'. This makes it possible for authenticated attackers, with Author-level access and above, to move or copy media files belonging to other users between folders, and to move protected files out of the protected directory.",
