WordPress Core is vulnerable to Information Exposure via the wp_ajax_sample_permalink() and wp_ajax_get_permalink() AJAX actions in various versions up to, and including, 7.1 due to a missing edit_post capability check on the supplied post ID. This makes it possible for authenticated attackers with Contributor-level access and above to disclose the slug and sample permalink of draft or pending posts authored by other users.
