=========================== Django 1.7.11 release notes =========================== *November 24, 2015* Django 1.7.11 fixes a security issue and a data loss bug in 1.7.10. Fixed settings leak possibility in ``date`` template filter =========================================================== If an application allows users to specify an unvalidated format for dates and passes this format to the :tfilter:`date` filter, e.g. ``{{ last_updated|date:user_date_format }}``, then a malicious user could obtain any secret in the application's settings by specifying a settings key instead of a date format. e.g. ``"SECRET_KEY"`` instead of ``"j/m/Y"``. To remedy this, the underlying function used by the ``date`` template filter, ``django.utils.formats.get_format()``, now only allows accessing the date/time formatting settings. Bugfixes ======== * Fixed a data loss possibility with :class:`~django.db.models.Prefetch` if ``to_attr`` is set to a ``ManyToManyField`` (:ticket:`25693`).
