Vulnerability Overview

The Melapress Login Security plugin for WordPress is vulnerable to Authentication Bypass due to missing authorization within the get_valid_user_based_on_token() function in versions 2.1.0 to 2.1.1. This makes it possible for unauthenticated attackers who know an arbitrary user meta value to bypass authentication checks and log in as that user.

Technical Analysis

REMEDIATION: Update to version 2.2.0, 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.
