{"cve":"CVE-2026-12406","nvd":{"published":"2026-07-09T08:16:45.850","modified":"2026-07-09T16:20:12.533","status":"Deferred","description":"The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.3.7. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.2/includes/Ajax.php#L27","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.2/includes/Ajax/Upload_Ajax.php#L257","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.2/includes/Ajax/Upload_Ajax.php#L271","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.2/includes/Frontend.php#L88","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.7/includes/Ajax.php#L27"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-12406","score":0.00561,"percentile":0.46707,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
