CVE-2026-12406: CWE-862 Missing Authorization in wedevs User Frontend: AI Powered Frontend Posting, User Directory, Profile Builder, Membership & User Registration
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.
AI Analysis
Technical Summary
CVE-2026-12406 is an authorization bypass vulnerability (CWE-862) in the User Frontend: AI Powered Frontend Posting, User Directory, Profile Builder, Membership & User Registration WordPress plugin by wedevs. The plugin fails to properly verify that a user is authorized to perform certain actions, specifically the deletion of media attachments via the wpuf_file_del AJAX action. Because the valid wpuf_nonce value is localized into publicly accessible JavaScript objects on pages rendering the WPUF shortcode, unauthenticated attackers can exploit this to delete arbitrary media attachments whose post_author is 0. This affects all versions up to and including 4.3.7.
Potential Impact
An unauthenticated attacker can delete arbitrary media attachments associated with guest or registration-form uploads on affected WordPress sites. This results in integrity loss of media content but does not impact confidentiality or availability. The CVSS 3.1 base score is 5.3 (medium severity), reflecting network attack vector, low complexity, no privileges required, no user interaction, unchanged scope, no confidentiality impact, low integrity impact, and no availability impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid rendering the WPUF shortcode on publicly accessible front-end pages to prevent exposure of the valid nonce in JavaScript objects. Monitor vendor channels for updates and apply patches promptly once released.
