Django Weblog: Django security releases issued: 1.11.5 and 1.10.8

Programing, Python, by admin.

In accordance with our security release policy, the Django team is issuing Django 1.11.5 and Django 1.10.8. These release addresses the security issue detailed below. We encourage all users of Django to upgrade as soon as possible.

CVE-2017-12794: Possible XSS in traceback section of technical 500 debug page

In older versions, HTML autoescaping was disabled in a portion of the template
for the technical 500 debug page. Given the right circumstances, this allowed
a cross-site scripting attack. This vulnerability shouldn’t affect most
production sites since you shouldn’t run with DEBUG = True (which makes
this page accessible) in your production settings.

Thanks Charles Bideau for reporting this issue.

Affected supported versions

  • Django master development branch
  • Django 1.11
  • Django 1.10

Per our supported versions policy, Django 1.9 is no longer supported. Django 1.8 is unaffected.


Patches to resolve the issues have been applied to Django’s master development branch and
the 1.11 and 1.10 release branches. The patches may be obtained from the following changesets:

The following releases have been issued:

General notes regarding security reporting

As always, we ask that potential security issues be reported via
private email to, and not via Django’s
Trac instance or the django-developers list. Please see our security
