Flexible Refund for WooCommerce – EU One Click Return < 1.0.52 - Authenticated (Customer+) Stored Cross-Site Scripting

Description

The Flexible Refund for WooCommerce – EU One Click Return plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.0.51 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with customer-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
