## Description

The Razorpay for WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference via the Magic Checkout coupon-apply REST endpoint (/wp-json/1cc/v1/coupon/apply) in all versions up to, and including, 4.8.8, due to the route's permission callback always returning true and the handler not checking that the caller is tied to the supplied 'order_id'. This makes it possible for unauthenticated attackers to rebuild the cart from any customer's order and read that order's value through the discount amount returned for a coupon.
