#13177 closed (fixed)

Unescaped user input in the Admin interface

Reported by: nomulous Owned by: nobody
Component: contrib.admin Version: 1.1
Severity: Keywords:
Cc: Triage Stage: Accepted
Has patch: yes Needs documentation: no
Needs tests: yes Patch needs improvement: no
Easy pickings: UI/UX:


Steps to reproduce:

  1. Go into the Django User Admin interface
  2. Open a given user
  3. Enter <script>alert('asdf')</script> into the First Name field
  4. Press "Save and Continue Editing"

Basically, a {% firstof %} tag in the Admin templates isn't escaping the user's First name. This can be fixed by putting simple {% filter force_escape %} around it.

The bug can be found in /django/contrib/admin/templates/admin/base.html, a modifired version of which is attached.

Also, ticket #10912 deals with escaping of template tags... should be an overall fix.
