This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to delete arbitrary media attachments whose post_author is 0, such as guest and registration-form uploads, via the wpuf_file_del AJAX action. This is exploitable by unauthenticated visitors on any site where a WPUF shortcode is rendered on a front-end page, as this causes the valid wpuf_nonce value to be localized into publicly accessible JavaScript objects (wpuf_upload and wpuf_frontend), satisfying the sole access control gate."}], "lastModified": "2026-07-09T16:20:12.533", "sourceIdentifier": "security@wordfence.com"}
