Vulnerability Overview

The Advanced Google reCAPTCHA plugin for WordPress is vulnerable to IP unblocking in all versions up to, and including, 1.25. This is due to the plugin not utilizing a strong unique key when generating an unblock request. This makes it possible for unauthenticated attackers to unblock their IP after being locked out due to too many bad password attempts

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-340: Generation of Predictable Numbers or Identifiers

How does WordSec protect against this?
