The WooCommerce plugin for WordPress is vulnerable to HTML Injection in all versions up to, and including, 9.0.2. This is due to the plugin not properly neutralizing HTML elements from submitted order forms. This makes it possible for unauthenticated attackers to inject arbitrary HTML that will render when the administrator views order form submissions.
The WooCommerce WordPress plugin before 6.2.1 does not have proper authorisation check when deleting reviews, which could allow any authenticated users, such as subscriber to delete arbitrary comment
The WooCommerce WordPress plugin before 6.6.0 is vulnerable to stored HTML injection due to lack of escaping and sanitizing in the payment gateway titles
When taxes are enabled, the "Additional tax classes" field was not properly sanitised or escaped before being output back in the admin dashboard, allowing high privilege users such as admin to use XSS payloads even when the unfiltered_html is disabled
