What fixes it

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 a gallery setting before outputting it on a frontend 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 a gallery, including administrators.
