The Adminify WordPress plugin before 4.2.10 does not perform per-user read-capability checks on the results returned by one of its administration search features, allowing users with a low-privilege role (Contributor) to disclose non-public content that WordPress would not otherwise expose to them, such as other authors' unpublished post titles, pending comment content, the site's Adminify WordPress plugin before 4.2.10 inventory, and user account names.
