CVE-2026-1492
User Registration & Membership <= 5.1.2 - Unauthenticated Privilege Escalation via Membership Registration
CRITICAL 9.8EPSS 28.0%
The User Registration & Membership – Custom Registration Form Builder, Custom Login Form, User Profile, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to improper privilege management in all versions up to, and including, 5.1.2. This is due to the plugin accepting a user-supplied role during membership registration without properly enforcing a server-side allowlist. This makes it possible for unauthenticated attackers to create administrator accounts by supplying a role value during membership registration.
