Technical description
The FooGallery – Responsive Photo Gallery, Image Viewer, Justified, Masonry & Carousel plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the default_gallery_title_size parameter in all versions up to, and including, 2.4.29 due to insufficient input sanitization and output escaping.
