Mozilla community member Michael reported that when a server responds with a Refresh header containing a javascript: URI, Firefox will redirect to the javascript: URI. If an attacker could inject a Refresh header into a server response, or could control the value that a site places in the Refresh header, they could use this vulnerability to perform an XSS attack and execute arbitrary JavaScript within the context of that site.
