Descriptions

The FluentAuth WordPress plugin before 1.0.2 prioritizes getting a visitor's IP address from certain HTTP headers over PHP's REMOTE_ADDR, which makes it possible to bypass the IP-based blocks set by the plugin.

El complemento FluentAuth para WordPress anterior a 1.0.2 prioriza obtener la dirección IP de un visitante de ciertos encabezados HTTP sobre REMOTE_ADDR de PHP, lo que hace posible evitar los bloqueos basados en IP establecidos por el complemento.

The FluentAuth plugin for WordPress is vulnerable to IP Address Spoofing in versions up to, and including, 1.0.1. This is due to insufficient restrictions on where the IP Address information is being retrieved for request logging and login restrictions. Attackers can supply the X-Forwarded-For header with with a different IP Address that will be logged and can be used to bypass settings that may have blocked out an IP address.
