# Django 1.10.7 release notes

April 4, 2017

Django 1.10.7 fixes two security issues and a bug in 1.10.6.

## 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()` and 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()` 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.

## Bugfixes

- Made admin's `RelatedFieldWidgetWrapper` use the wrapped widget's `value_omitted_from_data()` method (#27905).
- Fixed model form `default` fallback for `SelectMultiple` (#27993).
