Authentication Bypass Vulnerability in WPCOM Member Plugin for WordPress
CVE-2025-1475
9.8CRITICAL
Summary
The WPCOM Member plugin for WordPress is susceptible to an authentication bypass vulnerability across all versions up to and including 1.7.5. This vulnerability stems from inadequate verification of the 'user_phone' parameter during the login process. As a result, unauthenticated attackers could potentially gain access to any existing user account on the site, including administrative accounts, if SMS-based login is enabled. This could lead to unauthorized actions and a compromise of the site's security. Website administrators are urged to review their plugin configurations and apply any updates to mitigate this risk.
