Django 1.8.15 release notes
===========================

*September 26, 2016*

Django 1.8.15 fixes a security issue in 1.8.14.

CSRF protection bypass on a site with Google Analytics
======================================================

An interaction between Google Analytics and Django's cookie parsing could allow
an attacker to set arbitrary cookies leading to a bypass of CSRF protection.

The parser for ``request.COOKIES`` is simplified to better match the behavior
of browsers and to mitigate this attack. ``request.COOKIES`` may now contain
cookies that are invalid according to :rfc:`6265` but are possible to set via
``document.cookie``.
