This is due to the `express_pay_product_page_pay_for_order()` function logging users in based solely on a user-supplied billing email address during guest checkout for subscription products, without verifying email ownership, requiring a password, or validating a one-time token. This makes it possible for unauthenticated attackers to log in as any existing user, including administrators, by providing the target user's email address in the billing_details parameter, resulting in complete account takeover and site compromise."
