## Description

The Geo Controller plugin for WordPress is vulnerable to IP Address Spoofing via forwarding headers in all versions up to, and including, 9.0.2, due to the CFGP_IP::get() function trusting client-supplied headers such as X-Forwarded-For, X-Real-IP, Forwarded, Client-IP and (when Cloudflare support is enabled) CF-Connecting-IP without checking whether the request came from a trusted proxy or a Cloudflare address. This makes it possible for unauthenticated attackers to choose the IP address the plugin uses for geolocation, which can bypass the plugin's IP- and country-based restrictions such as Defender blocking and geo-targeted content or redirects.
