Description
The Robo Gallery plugin for WordPress is vulnerable to unauthorized modification of data in all versions up to, and including, 5.1.6 due to a missing per-post capability check and post type validation in the AJAX handler that saves the gallery hierarchy. The handler accepted a client-supplied tree and called wp_update_post on every ID with only a generic edit_posts check. This makes it possible for authenticated attackers, with contributor-level access and above, to change the parent and menu order of arbitrary posts on the site, including posts they are not permitted to edit.
