Flexible Refund and Return Order for WooCommerce < 1.0.43 - Incorrect Authorization to Authenticated (Contributor+) Refund Status Update

Description

The Flexible Refund and Return Order for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a misconfigured capability check on the 'create_refund' function in all versions up to, and including, 1.0.42. This makes it possible for authenticated attackers, with Contributor-level access and above, to update the status of refund requests, including approving and refusing refunds.
