Django 1.4.6 fixes one security issue present in previous Django releases in the 1.4 series, as well as one other bug.
This is the sixth bugfix/security release in the Django 1.4 series.
Django relies on user input in some cases (e.g.
django.contrib.auth.views.login()
, django.contrib.comments
, and
i18n) to redirect the user to an “on success” URL.
The security checks for these redirects (namely
django.utils.http.is_safe_url()
) didn’t check if the scheme is http(s)
and as such allowed javascript:...
URLs to be entered. If a developer
relied on is_safe_url()
to provide safe redirect targets and put such a
URL into a link, they could suffer from a XSS attack. This bug doesn’t affect
Django currently, since we only put this URL into the Location
response
header and browsers seem to ignore JavaScript there.

decorator. If you hit an AttributeError: 'Settings' object has no attribute
'_original_allowed_hosts'
exception, it’s probably fixed (#20636).Jun 09, 2017
