Recommendation: Monitor — no exploitation signal at the moment.

The Meta-box GalleryMeta plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'mb_gallery' custom post type in all versions up to, and including, 3.0.1. This makes it possible for authenticated attackers, with Author-level access and above, to create and publish galleries.
