Vulnerability Overview

The Antispam Bee plugin for WordPress is vulnerable to IP Address Spoofing in all versions up to, and including, 2.11.3 due to use of user-supplied HTTP headers as a primary method for IP retrieval. This makes it possible for unauthenticated attackers to bypass country blocking.

Technical Analysis

REMEDIATION: Update to version 2.11.4, or a newer patched version --- IDENTIFIER: CWE-807 (Reliance on Untrusted Inputs in a Security Decision) The product uses a protection mechanism that relies on the existence or values of an input, but the input can be modified by an untrusted actor in a way that bypasses the protection mechanism.
