The Envira Gallery WordPress plugin before 1.16.1 does not sanitise or escape user-supplied gallery display configuration values before storing them and outputting them 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 containing the affected gallery.
