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."}], "title": "User Frontend <= 4.3.7 - Missing Authorization to Unauthenticated Arbitrary Attachment Deletion via 'attach_id' Parameter", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/0049583a-0ad3-45e4-a29e-4b8c33d09857?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.7/includes/Ajax/Upload_Ajax.php#L271"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.7/includes/Ajax/Upload_Ajax.php#L257"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.7/includes/Ajax.php#L27"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.7/includes/Frontend.php#L88"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.2/includes/Ajax/Upload_Ajax.php#L271"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.2/includes/Ajax/Upload_Ajax.php#L257"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.2/includes/Ajax.php#L27"}, {"url": "https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.2/includes/Frontend.php#L88"}, {"url": "https://plugins.trac.wordpress.org/changeset?reponame=&old=3578622%40wp-user-frontend&new=3578622%40wp-user-frontend"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-862 Missing Authorization", "cweId": "CWE-862", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N", "baseScore": 5.3, "baseSeverity": "MEDIUM"}}], "credits": [{"lang": "en", "type": "finder", "value": "mrvincere"}], "timeline": [{"time": "2026-06-16T14:16:32.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-07-08T19:22:00.000Z", "lang": "en", "value": "Disclosed"}]}}}
