Vulnerability Overview

The PrivateContent plugin for WordPress is vulnerable to protection mechanism bypass due to the use of client side validation in versions up to, and including, 8.4.3. This is due to the plugin checking if an IP had been blocklist via client-side scripts rather than server-side. This makes it possible for unauthenticated attackers to bypass any login restrictions that may prevent a brute force attack.

Technical Analysis

REMEDIATION: Update to version 8.4.4, or a newer patched version --- IDENTIFIER: CWE-602 (Client-Side Enforcement of Server-Side Security) The product is composed of a server that relies on the client to implement a mechanism that is intended to protect the server.
