Description

The reCAPTCHA for WooCommerce plugin for WordPress is vulnerable to a CAPTCHA bypass via the WooCommerce registration form in versions 1.4.6 to 1.4.7. This is due to the registration check returning early for any request where XMLRPC_REQUEST is defined, while WooCommerce still processes a registration form posted to xmlrpc.php. This makes it possible for unauthenticated attackers to register customer accounts automatically without solving the reCAPTCHA.
