Overview

CVE-2026-6145 is a medium-severity vulnerability. It was published on May 14, 2026 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
