What is CVE-2025-34077?

An authentication bypass vulnerability in the WordPress Pie Register plugin allows unauthorized attackers to impersonate any user by sending specially crafted POST requests. By adjusting the 'social_site' parameter and affecting 'user_id_social_site', intruders can generate valid session cookies for any user, including admins. Once authenticated, these attackers can exploit the plugin's upload functionality to introduce malicious PHP code, potentially leading to remote code execution and compromising server integrity.
