# Django 2.1.5 release notes

January 4, 2019

Django 2.1.5 fixes a security issue and several bugs in 2.1.4.

## CVE-2019-3498: Content spoofing possibility in the default 404 page

An attacker could craft a malicious URL that could make spoofed content appear on the default page generated by the `django.views.defaults.page_not_found()` view.

The URL path is no longer displayed in the default 404 template and the `request_path` context variable is now quoted to fix the issue for custom templates that use the path.
