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 some of its gallery settings before outputting them on the gallery edit screen, allowing users with the Contributor role and above to store JavaScript that executes in the context of an administrator who opens the gallery for editing.
