Most of the remarks there seem to refer to Wordpress. Is that the only
place the vulnerability exists?
One page said to append: /"><script>alert(1)</script>
to your URL. "If you receive a JavaScript popup your template is
vulnerable to this attack." None of my sites return a popup. Should I
worry? (No Wordpress in use.)
