Description
The Pie Register – User Registration, Profiles & Content Restriction plugin for WordPress is vulnerable to a CAPTCHA bypass via the registration form's reCAPTCHA field in all versions up to, and including, 3.8.4.18, due to the server-side reCAPTCHA check on registration only running when the 'piereg_enable_recaptcha' setting is enabled, a setting the plugin never creates or saves. This makes it possible for unauthenticated attackers to submit the registration form without solving the reCAPTCHA shown on it and create accounts automatically, bypassing the bot protection the site owner configured.
