Technical details
The vulnerability is an access control bypass (CWE-284) in the SureCart WordPress REST API endpoints. The plugin's checkout creation and confirmation endpoints (/wp-json/surecart/v1/checkouts and /wp-json/surecart/v1/checkouts/{id}/confirm) do not check the WordPress site's users_can_register setting before creating new user accounts and issuing authenticated sessions. An unauthenticated attacker can POST to these endpoints to create a checkout, PATCH it with email/password/name credentials, and confirm it to receive a valid wordpress_logged_in cookie and a new subscriber account, completely bypassing the site's registration restrictions. No payment is required; the checkout remains in draft status. The vulnerability was fixed in version 4.7.0.
