Vulnerability Overview

The User Registration & Membership plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 4.1.2. This is due to incorrect authentication in the 'confirm_payment()' function. This makes it possible for unauthenticated attackers to log in an existing user on the site, even an administrator.

Technical Analysis

REMEDIATION: Update to version 4.1.3, or a newer patched version --- IDENTIFIER: CWE-288 (Authentication Bypass Using an Alternate Path or Channel) The product requires authentication, but the product has an alternate path or channel that does not require authentication.
