Description

The SureCart plugin for WordPress is vulnerable to Open Redirect via the 'success_url' parameter on the add payment method page in all versions up to, and including, 4.12.1 due to insufficient validation of the redirect URL, which was only passed through esc_url and not restricted to the site's own host. This makes it possible for unauthenticated attackers to redirect customers to arbitrary external sites after they add a payment method, provided they can trick a logged-in customer into following a crafted link.
