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

REMEDIATION: Update to version 5.0.26, or a newer patched version --- IDENTIFIER: 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.
