Vulnerability Overview

The Hide My WP Ghost plugin for WordPress is vulnerable to CAPTCHA Bypass in versions up to, and including, 5.0.25. This is due a logic flaw within the brute_math_authenticate function. This makes it possible for unauthenticated attackers to bypass CAPTCHA by omitting the `brute_ck` parameter from the authentication request.

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-807: Reliance on Untrusted Inputs in a Security Decision

The product uses a protection mechanism that relies on the existence or values of an input, but the input can be modified by an untrusted actor in a way that bypasses the protection mechanism.

Remediation

Update to version 5.0.26, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Hide My WP Ghost 5.0.26 closes this, and updating the plugin is the step that ends it.
