What the vulnerability does
01Description
The Coupon Affiliates – Affiliate Plugin for WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the commission_summary parameter in all versions up to, and including, .6.3.0 due to insufficient input sanitization and output escaping.
