Flexible Refund and Return Order for WooCommerce < 1.0.39 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Order Refund

Description

The Flexible Refund and Return Order for WooCommerce plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.0.38 via the save_refund_request() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to submit refund requests for arbitrary orders that they do not own.
