YITH WooCommerce Product Add-Ons < 4.2.1 - Missing Authorization

Description The YITH WooCommerce Product Add-Ons plugin for WordPress is vulnerable to unauthorized functionality due to a missing capability check on two of its AJAX actions in versions up to, and including, 4.2.0. This makes it possible for unauthenticated attackers to make use of this functionality and allows them to enable and disable blocks and addons.
