WP Plugin Advanced Custom Fields Extended Improper Privilege Management Vulnerability - CVE-2025-14533

The Advanced Custom Fields: Extended plugin for WordPress is vulnerable to Privilege Escalation in all versions up to and including 0.9.2.1. This is due to the insert_user function not restricting the roles with which a user can register. This makes it possible for unauthenticated attackers to supply the administrator role during registration and gain administrator access to the site. Note: The vulnerability can only be exploited if role is mapped to the custom field.
