Classified Listing < 5.4.4 - Contributor+ Unpublished Post Content Disclosure via rtcl_block_css_get_posts

Description

The plugin does not perform a capability or ownership check on an AJAX action that returns a post's content, allowing users with contributor-level access and above to read the content of any post, page, or custom post type on the site — including drafts, pending, and private posts owned by other users — regardless of ownership.
