The Envira Gallery WordPress plugin before 1.16.1 does not sanitise and escape a gallery item identifier before outputting it in an image tag attribute, allowing users with the Author role and above to inject arbitrary web scripts that execute when any visitor, including an administrator, views a page embedding the gallery.
