A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.
Description
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.
