The Simpler Checkout plugin for WordPress is vulnerable to Authentication Bypass in versions 0.7.0 to 1.1.9. This is due to the plugin not properly verifying a users identity prior to logging them in as an admin through the simplerwc_woocommerce_order_created() function. This makes it possible for unauthenticated attackers to log in as other users based on their order ID, which can be an administrator if a site admin has placed a test order.
A product requires authentication, but the product has an alternate path or channel that does not require authentication.
