## Description

The King Addons for Elementor plugin for WordPress is vulnerable to Sensitive Information Exposure via the Dynamic Posts Grid filter and load more AJAX actions (king_addons_dynamic_posts_grid_filter and king_addons_dynamic_posts_grid_load_more) in all versions up to, and including, 51.1.87. This is due to the handlers taking the post types, filter taxonomy and custom-field (meta key) mapping straight from the request, protected only by a nonce that is printed on every front-end page. This makes it possible for unauthenticated attackers to list published posts of non-public post types (for example WooCommerce coupon codes) and to read arbitrary post meta values of published posts, which are rendered into the response.
