AA Block country <= 1.0.1 - Unauthenticated IP Address Spoofing via X-Forwarded-For Header

Use of Less Trusted Source
CVE CVE-2025-13694
CVSS Medium (5.3)
Publicly Published January 6, 2026

Researcher Ivan Cese
Description

The AA Block Country plugin for WordPress is vulnerable to IP Address Spoofing in versions up to, and including, 1.0.1. This is due to the plugin trusting user-supplied headers such as HTTP_X_FORWARDED_FOR to determine the client's IP address without proper validation or considering if the server is behind a trusted proxy. This makes it possible for unauthenticated attackers to bypass IP-based access restrictions by spoofing their IP address via the X-Forwarded-For header.
