Vulnerability Overview

The Spam Free WordPress plugin for WordPress is vulnerable to IP Protection Bypass in versions up to, and including, 1.9.3 via the sfw_comment_post_authentication() function due to the fact that the plugin relies on a value that can be user-supplied ('comment_ip' parameter) for the IP address that is checked against the blocklist. This makes it possible for unauthenticated attackers to bypass comment restrictions

Technical Analysis

REMEDIATION: Update to version 2.0, or a newer patched version --- IDENTIFIER: CWE-284 (Improper Access Control) The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
