CVE-2023-0581: Lcweb Privatecontent

Medium severity, CVSS 5.3. EPSS: 0.7% chance of exploitation in the next 30 days.

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.

Affected products

• Lcweb Privatecontent: before 8.4.4 (fixed in 8.4.4)
