User Registration & Membership <= 5.1.2 - Unauthenticated Privilege Escalation via Membership Registration

Published Mar 3, 2026 · Updated Apr 8, 2026 · Assigned by Wordfence

Vendor: WPEverest Product: User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder Category: Web / CMS

Description

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.
