Django Permissions Privileges and Access Controls Vulnerability - CVE-2010-4534

The administrative interface in django.contrib.admin in Django before 1.1.3 1.2.x before 1.2.4 and 1.3.x before 1.3 beta 1 does not properly restrict use of the query string to perform certain object filtering which allows remote authenticated users to obtain sensitive information via a series of requests containing regular expressions as demonstrated by a created_by__password__regex parameter.
