APIExperts Square for WooCommerce < 4.3 - Reflected Cross-Site Scripting

Description

The APIExperts Square for WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 4.2.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
