ImportanceReview GuidanceRequires Scanning Tool
MediumMerge After Cursory ReviewYes (DefectDojo)

This codemod sets the most secure parameters when Django applications call set_cookie on a response object. Without these parameters, your Django application cookies may be vulnerable to being intercepted and used to gain access to sensitive data.

The changes from this codemod look like this:

 from django.shortcuts import render
def index(request):
resp = render(request, 'index.html')
- resp.set_cookie('custom_cookie', 'value')
+ resp.set_cookie('custom_cookie', 'value', secure=True, httponly=True, samesite='Lax')
return resp

F.A.Q.

Why is this codemod marked as Merge After Cursory Review?

Our change provides the most secure way to create cookies in Django. However, it's possible you have configured your Django application configurations to use secure cookies. In these cases, using the default parameters for set_cookie is safe.
