WordPress Pie Register Plugin ≤ 3.7.1.4 Authentication Bypass RCE

Published Jul 9, 2025 CVSS 4.0 · 10 Critical EPSS 16.5% KEV · Not listed
Description
An authentication bypass vulnerability exists in the WordPress Pie Register plugin ≤ 3.7.1.4 that allows unauthenticated attackers to impersonate arbitrary users by submitting a crafted POST request to the login endpoint. By setting social_site=true and manipulating the user_id_social_site parameter, an attacker can generate a valid WordPress session cookie for any user ID, including administrators. Once authenticated, the attacker may exploit plugin upload functionality to install a malicious plugin containing arbitrary PHP code, resulting in remote code execution on the underlying server.
