Djangoproject : Security Vulnerabilities, CVEs, Published In 2011 (CSRF)

The CSRF protection mechanism in Django through 1.2.7 and 1.3.x through 1.3.1 does not properly handle web-server configurations supporting arbitrary HTTP Host headers, which allows remote attackers to trigger unauthenticated forged requests via vectors involving a DNS CNAME record and a web page containing JavaScript code.

Django 1.1.x before 1.1.4 and 1.2.x before 1.2.5 does not properly validate HTTP requests that contain an X-Requested-With header, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via forged AJAX requests that leverage a "combination of browser plugins and redirects," a related issue to CVE-2011-0447.
