MB Custom Post Types & Custom Taxonomies 2.4.0 - 2.12.2 - Contributor+ Post Type Definition and Non-Public Post Metadata Disclosure via Export

The MB Custom Post Types & Custom Taxonomies WordPress plugin before 2.12.3 does not perform a capability check in its export feature, allowing users with a role as low as Contributor to read the configuration of admin-only custom post types and taxonomies, as well as the titles, dates, statuses and some stored content of other users' non-public posts and pages.
