## Description

The King Addons for Elementor plugin for WordPress is vulnerable to Sensitive Information Exposure via the Posts Grid and WooCommerce Grid AJAX filtering actions (king_addons_filter_grid_posts, king_addons_filter_woocommerce_products and their count actions) in all versions up to, and including, 51.1.87. This is due to the handlers building the query from a visitor-supplied 'grid_settings' array, protected only by a nonce that is printed on public pages, and to several query branches (manual selection, current query and the product grid) not limiting the post status. In the admin-ajax context these queries include draft, pending and scheduled posts. This makes it possible for unauthenticated attackers to view the titles and content of unpublished posts, pages and products.
