WordPress core is vulnerable to Missing Authorization in all versions up to and including 6.9.1. This is due to a missing capability check on the uploadedToTitle and uploadedToLink fields in the wp_prepare_attachment_for_js() function.
When querying media attachments via the AJAX query-attachments endpoint, the response includes the parent post's title without verifying whether the current user has read_post permission on the parent post. This makes it possible for authenticated attackers with Author-level access to discover the titles of private, draft, and restricted posts that have media attachments.
Not sure which version you run? Run a passive check — it reads public files only.
