PrivateContent <= 8.4.3 - Protection Mechanism Bypass

Client-Side Enforcement of Server-Side Security
CVE CVE-2023-0581
CVSS 5.3 (Medium)
Publicly Published January 30, 2023

Researcher Riccardo Granata


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.
