# Notes de publication de Django 1.9.13

*4 avril 2017*

Django 1.9.13 fixes two security issues and a bug in 1.9.12. This is the final
release of the 1.9.x series.

## CVE-2017-7233: Open redirect and possible XSS attack via user-supplied numeric redirect URLs

Django relies on user input in some cases  (e.g.
[`django.contrib.auth.views.login()`](/fr/1.11/topics/auth/default/#django.contrib.auth.views.login) and [i18n](/fr/1.11/topics/i18n/))
to redirect the user to an « on success » URL. The security check for these
redirects (namely `django.utils.http.is_safe_url()`) considered some numeric
URLs (e.g. `http:999999999`) « safe » when they shouldn’t be.

Also, if a developer relies on `is_safe_url()` to provide safe redirect
targets and puts such a URL into a link, they could suffer from an XSS attack.

## CVE-2017-7234: Open redirect vulnerability in `django.views.static.serve()`

A maliciously crafted URL to a Django site using the
[`serve()`](/fr/1.11/ref/views/#django.views.static.serve) view could redirect to any other domain. The
view no longer does any redirects as they don’t provide any known, useful
functionality.

Note, however, that this view has always carried a warning that it is not
hardened for production use and should be used only as a development aid.

## Correction de bogues

- Fixed a regression in the `timesince` and `timeuntil` filters that caused
  incorrect results for dates in a leap year ([#27637](https://code.djangoproject.com/ticket/27637)).
