Django 3.2.2 release notes
|
|
==========================
|
|
|
|
*May 6, 2021*
|
|
|
|
Django 3.2.2 fixes a security issue and a bug in 3.2.1.
|
|
|
|
CVE-2021-32052: Header injection possibility since ``URLValidator`` accepted newlines in input on Python 3.9.5+
|
|
===============================================================================================================
|
|
|
|
On Python 3.9.5+, :class:`~django.core.validators.URLValidator` didn't prohibit
|
|
newlines and tabs. If you used values with newlines in HTTP response, you could
|
|
suffer from header injection attacks. Django itself wasn't vulnerable because
|
|
:class:`~django.http.HttpResponse` prohibits newlines in HTTP headers.
|
|
|
|
Moreover, the ``URLField`` form field which uses ``URLValidator`` silently
|
|
removes newlines and tabs on Python 3.9.5+, so the possibility of newlines
|
|
entering your data only existed if you are using this validator outside of the
|
|
form fields.
|
|
|
|
This issue was introduced by the :bpo:`43882` fix.

|
contained ``OrderBy`` expressions (:ticket:`32714`).
