Django 1.1.3 release notes
|
|
==========================
|
|
|
|
Welcome to Django 1.1.3!
|
|
|
|
This is the third "bugfix" release in the Django 1.1 series,
|
|
improving the stability and performance of the Django 1.1 codebase.
|
|
|
|
With one exception, Django 1.1.3 maintains backwards compatibility
|
|
with Django 1.1.2. It also contains a number of fixes and other
|
|
improvements. Django 1.1.2 is a recommended upgrade for any
|
|
development or deployment currently using or targeting Django 1.1.
|
|
|
|
For full details on the new features, backwards incompatibilities, and
|
|
deprecated features in the 1.1 branch, see the :doc:`/releases/1.1`.

Restricted filters in admin interface
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The Django administrative interface, django.contrib.admin, supports
|
|
filtering of displayed lists of objects by fields on the corresponding
|
|
models, including across database-level relationships. This is
|
|
implemented by passing lookup arguments in the querystring portion of
|
|
the URL, and options on the ModelAdmin class allow developers to
|
|
specify particular fields or relationships which will generate
|
|
automatic links for filtering.
|
|
|
|
One historically-undocumented and -unofficially-supported feature has
|
|
been the ability for a user with sufficient knowledge of a model's
|
|
structure and the format of these lookup arguments to invent useful
|
|
new filters on the fly by manipulating the querystring.
|
|
|
|
However, it has been demonstrated that this can be abused to gain
|
|
access to information outside of an admin user's permissions; for
|
|
example, an attacker with access to the admin and sufficient knowledge
|
|
of model structure and relations could construct query strings which --
|
|
with repeated use of regular-expression lookups supported by the
|
|
Django database API -- expose sensitive information such as users'
|
|
password hashes.
|
|
|
|
To remedy this, django.contrib.admin will now validate that
|
|
querystring lookup arguments either specify only fields on the model
|
|
being viewed, or cross relations which have been explicitly
|
|
whitelisted by the application developer using the pre-existing
|
|
mechanism mentioned above. This is backwards-incompatible for any
|
|
users relying on the prior ability to insert arbitrary lookups.
