"Nick Brunn reported a possible cross-site scripting vulnerability in
python-django, a high-level Python web development framework.

The is_safe_url utility function used to validate that a used URL is
on the current host to avoid potentially dangerous redirects from
maliciously-constructed querystrings, worked as intended for HTTP and
HTTPS URLs, but permitted redirects to other schemes, such as
javascript:.

The is_safe_url function has been modified to properly recognize and
reject URLs which specify a scheme other than HTTP or HTTPS, to
prevent cross-site scripting attacks through redirecting to other
schemes."
