WPC Grouped Product for WooCommerce < 4.4.3 - Missing Authorization

Description

The WPC Grouped Product for WooCommerce plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the ajax_update_search_settings, ajax_get_plugins, and ajax_get_essential_kit functions in all versions up to, and including, 4.4.2. This makes it possible for authenticated attackers, with subscriber-level access and above, to perform unauthorized actions.
