The The Post Grid – Shortcode, Gutenberg Blocks and Elementor Addon for Post Grid plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 7.7.11 via the post_query_guten and post_query functions. This makes it possible for authenticated attackers, with contributor-level access and above, to extract information from posts that are not public (i.e. draft, future, etc..).
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
