## What is CVE-2026-6145?

CVE-2026-6145 is a medium-severity missing authorization vulnerability in wpeverest User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder, published on 14 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The User Registration & Membership plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 5.1.5. This is due to the is_admin_creation_process() method relying solely on the presence of action=createuser in the $_REQUEST superglobal without performing any authentication or capability check. This makes it possible for unauthenticated attackers to bypass the admin approval requirement when registering new accounts via the fallback submission path.

Weakness: CWE-862 (Missing Authorization)
