 "title": "Nexter Extension <= 4.7.12 - Authenticated (Contributor+) Sensitive Information Exposure via Display Conditions Pickers",
 "description": "The Nexter Extension plugin for WordPress is vulnerable to Sensitive Information Exposure via the Display Conditions pickers ('nxt_singular_archives_filters_ajax' AJAX action) in all versions up to, and including, 4.7.12. This is due to the action passing request-supplied WP_Query and WP_User_Query arguments through and returning the results without checking that the user can read each returned post or has the list_users capability. This makes it possible for authenticated attackers with Contributor-level access and above to see the titles of other users' private, draft and pending posts and to list the site's users.",
