The Slim SEO – A Fast & Automated SEO Plugin For WordPress plugin for WordPress is vulnerable to Unauthorized Private Content Disclosure in all versions up to, and including, 4.9.8 via the /wp-json/slim-seo/meta-tags/ai REST API endpoint. This is due to the endpoint's permission_callback performing only a top-level edit_posts capability check without verifying that the requesting user has read access to the specific post supplied via the object.ID parameter, allowing the generate function to pass the attacker-controlled post ID to Data::get_post_content(), which calls get_post() regardless of post status or ownership. This makes it possible for authenticated attackers with Contributor-level access and above to retrieve AI-generated summaries of the raw post_content of arbitrary posts they are not authorized to view — including private posts, drafts, pending, future, and password-protected content authored by other users — with the substance of the protected content disclosed via the HTTP response.
