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.
Bugfixes
- Fixed compatibility with mysqlclient 1.3.14 (#30013).
- Fixed a schema corruption issue on SQLite 3.26+. You might have to drop and
rebuild your SQLite database if you applied a migration while using an older
version of Django with SQLite 3.26 or later (#29182).
- Prevented SQLite schema alterations while foreign key checks are enabled to
avoid the possibility of schema corruption (#30023).
- Fixed a regression in Django 2.1.4 (which enabled keep-alive connections)
where request body data isn't properly consumed for such connections
(#30015).
- Fixed a regression in Django 2.1.4 where
InlineModelAdmin.has_change_permission() is incorrectly called with a
non-None obj argument during an object add (#30050).
