# Django 1.7.11 リリースノート

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 `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.

## バグ修正

- Fixed a data loss possibility with `Prefetch` if `to_attr` is set to a `ManyToManyField` (#25693).
