Razorpay for WooCommerce < 4.7.9 - Unauthenticated Order Modification

Description

The plugin is vulnerable to unauthorized modification of data due to a missing capability check on the getCouponList() function due to the checkAuthCredentials() permission callback always returning true, providing no actual authentication. This makes it possible for unauthenticated attackers to modify the billing and shipping contact information (email and phone) of any WooCommerce order by knowing or guessing the order ID.
