Description
The reCAPTCHA for WooCommerce plugin for WordPress is vulnerable to a CAPTCHA bypass via the WooCommerce login form in all versions up to, and including, 1.4.7. This is due to the login check only running when the 'woocommerce-login-nonce' field is present, although WooCommerce also accepts the login nonce as '_wpnonce'. The check is also skipped for any request sent to xmlrpc.php, where WooCommerce still processes a posted login form. This makes it possible for unauthenticated attackers to make WooCommerce login attempts without solving the reCAPTCHA, which enables automated brute-force attacks.
