Description
The Formidable Forms plugin for WordPress is vulnerable to IP Spoofing in versions up to, and including, 6.0.1 due to a reliance on various untrusted headers (e.g., 'Client-Ip', 'CF-CONNECTING-IP', etc.) to retrieve the IP address of a client performing a form submission. This makes it possible for unauthenticated users to bypass the plugin's anti-spam protections.
