Description
The reCAPTCHA for WooCommerce plugin for WordPress is vulnerable to a CAPTCHA bypass on the WooCommerce lost password (Reset Password) form in all versions up to, and including, 1.4.7. The check only ran when the 'woocommerce-lost-password-nonce' field was present, but WooCommerce also accepts the nonce as '_wpnonce'. The check was also skipped whenever '/wp-login.php' appeared anywhere in the request URI, for example in the query string of a request to admin-ajax.php. This makes it possible for unauthenticated attackers to submit automated password reset requests without solving the reCAPTCHA.
