Checkout Field Editor for WooCommerce – Checkout Manager <= 3.0.5 - Authenticated (Shop manager+) Stored Cross-Site Scripting

Description

The Checkout Field Editor for WooCommerce – Checkout Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.0.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with shop manager-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
