Published Aug 31, 2024 · Updated Apr 8, 2026 · Assigned by Wordfence

Description

The WP Cerber Security plugin for WordPress is vulnerable to IP Protection bypass in versions up to, and including 9.4 due to the plugin improperly checking for a visitor's IP address. This makes it possible for an attacker whose IP address has been blocked to bypass this control by setting the X-Forwarded-For: HTTP header to an IP Address that hasn't been blocked.
