The Robo Gallery WordPress plugin before 5.2.6 does not sanitise and escape some of its image settings before outputting them in a gallery page, allowing users with the Author role and above to perform Stored Cross-Site Scripting attacks that execute in the browser of any visitor viewing the gallery, including administrators, even where the unfiltered_html capability is disallowed such as on multisite.
