## Description

The UiCore Elements plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'current_query' parameter of the public uielem/v1/load_more REST endpoint used by the Advanced Post widgets in all versions up to, and including, 1.3.18, due to the client-supplied JSON query being decoded and passed unfiltered into WP_Query. This makes it possible for unauthenticated attackers to set arbitrary query variables such as post_status and post_type and retrieve the rendered content of draft, private, or otherwise non-public posts, provided a post widget configured to use the 'current' query exists on the site.
