## Description

The The Post Grid plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'rttpg_block_css_get_posts' AJAX action (block CSS loader) in all versions up to, and including, 7.9.8, due to an insufficient 'read_post' capability check that does not account for post passwords and returns the raw post_content of any readable post. This makes it possible for authenticated attackers, with Contributor-level access and above, to retrieve the raw content of password-protected posts by supplying their post ID.
