Potential sensitive information disclosed in error reports

django-registration is a user-registration application for Django.


The django-registration package provides tools for implementing user-account registration flows in the Django web framework. In django-registration prior to 3.1.2, the base user-account registration view did not properly apply filters to sensitive data, with the result that sensitive data could be included in error reports rather than removed automatically by Django.

Triggering this requires the following conditions:

Under these conditions, recipients of the detailed error report will see all submitted data from the account-registration attempt, which may include the user's proposed credentials (such as a password).


As of version 3.1.2, django-registration properly applies Django's sensitive_post_parameters() decorator to the base user-registration view, which will cause all data from the HTTP request body to be filtered from detailed error reports in the event of a server-side crash during user account registration.

Note that as applied, this filters all HTTP request data from error reports. To selectively allow some fields but not others, see Django's own documentation (in references) and the notes below for how to apply sensitive_post_parameters() manually to a particular codebase's RegistrationView subclass(es).


Users who cannot upgrade quickly can apply the django.views.decorators.debug.sensitive_post_parameters() decorator to their own registration views. The decorator should be applied on the dispatch() method of the appropriate RegistrationView class, using Django's method_decorator() helper. For example:

from django.utils.decorators import method_decorator
from django.views.decorators.debug import sensitive_post_parameters

from django_registration.views import RegistrationView

class MyRegistrationView(RegistrationView):
    A RegistrationView subclass manually protected against sensitive information disclosure
    in error reports.

    def dispatch(self, *args, **kwargs):
        return super().dispatch(*args, **kwargs)
