Advisory
Source description from Wordfence Intelligence, credited to konagash.
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.
