## Description

The The Post Grid plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'rttpg/v1/builder' and 'rttpg/v1/query' REST API endpoints and the grid's full-content and excerpt rendering in all versions up to, and including, 7.9.9. This is due to the plugin returning raw post_content of published posts without passing it through the 'the_content' filter, which membership and content-restriction plugins use to hide content from users who are not allowed to read it. This makes it possible for authenticated attackers with Contributor-level access and above to read the full content of published posts that a membership or content-restriction plugin restricts. Grids set to show full content or excerpts can also show that content to visitors.
