What is CVE-2025-11707?

The Login Lockdown & Protection plugin for WordPress is susceptible to an IP Block Bypass vulnerability across all versions up to and including 2.14. This flaw arises from an insufficiently random $unblock_key, enabling unauthenticated users who possess knowledge of an administrative user's email to generate valid unblock keys. As a result, malicious actors may successfully bypass IP blocks initiated due to invalid login attempts, posing significant security risks.

Affected Version(s)

Login Lockdown & Protection * <= 2.14
