django-extra (S610)#
Derived from the flake8-bandit linter.
This rule is unstable and in preview. The --preview flag is required for use.
What it does#
Checks for uses of Django's extra function.
Why is this bad?#
Django's extra function can be used to execute arbitrary SQL queries,
which can in turn lead to SQL injection vulnerabilities.
Example#
from django.contrib.auth.models import User
User.objects.all().extra(select={"test": "%secure" % "nos"})
