## Description

The Robo Gallery plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 5.1.6 due to a missing post type and capability check in the AJAX action that renders the album hierarchy meta box. This makes it possible for authenticated attackers, with contributor-level access and above, to read the titles of arbitrary pages, galleries and other hierarchical posts, including private, draft and pending ones.
