## Description

The FooGallery Photo Gallery plugin for WordPress is vulnerable to Sensitive Information Exposure via the foogallery shortcode, the gallery block and the block-renderer REST route in all versions up to, and including, 3.3.17. This is due to the gallery renderer loading a gallery by its ID without checking the gallery's post status. This makes it possible for authenticated attackers, with Contributor-level access and above, to embed or preview private and draft galleries they are not permitted to read and view their images and captions.
