	It appears that Safari does not enforce any kind of access
	restrictions for XMLHTTPRequests on FILE: scheme URLs. As a
	result, any HTML file on the local file system that is opened in
	Safari can read any file that the user has access to (and, of
	course, it can upload those files too). Here's a little
	proof-of-concept. Copy and paste this into a local HTML file and
	open it in Safari. It will display the contents of /etc/passwd.

	#!/bin/bash
	set -ex
