This module allows you to specify an HTTP header name to determine the client's IP address.
The module doesn't sufficiently handle all cases under the scenario if Drupal Core settings $settings['reverse_proxy'] is set to TRUE and $settings['reverse_proxy_addresses'] is configured.
This vulnerability allows an attacker to spoof a request IP address (as Drupal sees it), potentially bypassing a variety of controls.
