## Description

The Pixel Tag Manager for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data via the pmw_pixels_save, pmw_clean_debug_logs and pmw_notice_dismiss AJAX actions in all versions up to, and including, 2.2.2, due to a missing capability check in the admin_safe_ajax_call() function. That function relied only on is_admin(), which is true for every admin-ajax.php request, and on a pmw_ajax_nonce that the plugin printed in its admin notices on every wp-admin screen to any logged-in user. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change the plugin's tracking and conversion API settings (pixel IDs, API tokens, data-sharing options) and to clear its debug logs.
