The endpoint is registered as wp_ajax_nopriv_{provider}-signup with a nonce that is emitted on the public login page. This makes it possible for unauthenticated attackers to elevate their privileges to Administrator by creating a new user with an attacker-chosen role, provided a social-login provider is registered and open registration is enabled."
