CVE-2026-14568Public exploitNetwork attack vector

Unauthenticated media deletion via unchecked attachment ownership

Published Jul 27, 2026 · Updated Jul 27, 2026

Improper authentication in WP User Frontend before 4.3.8 allows remote attackers to permanently delete author-less media attachments. The wpuf_file_del AJAX action accepts a guest nonce and attachment ID, then deletes the database row and file without confirming an authenticated owner. Any site exposing a public plugin form and containing a post_author=0 attachment, including guest uploads or placeholder media, is affected; deletion is permanent.
