# Django 2.2.3 release notes

July 1, 2019

Django 2.2.3 fixes a security issue and several bugs in 2.2.2. Also, the latest string translations from Transifex are incorporated.

## CVE-2019-12781: Incorrect HTTP detection with reverse-proxy connecting via HTTPS

When deployed behind a reverse-proxy connecting to Django via HTTPS, `django.http.HttpRequest.scheme` would incorrectly detect client requests made via HTTP as using HTTPS. This entails incorrect results for `is_secure()`, and `build_absolute_uri()`, and that HTTP requests would not be redirected to HTTPS in accordance with `SECURE_SSL_REDIRECT`.

`HttpRequest.scheme` now respects `SECURE_PROXY_SSL_HEADER`, if it is configured, and the appropriate header is set on the request, for both HTTP and HTTPS requests.

If you deploy Django behind a reverse-proxy that forwards HTTP requests, and that connects to Django via HTTPS, be sure to verify that your application correctly handles code paths relying on `scheme`, `is_secure()`, `build_absolute_uri()`, and `SECURE_SSL_REDIRECT`.

### Perbaikan kesalahan

- Fixed a regression in Django 2.2 where `Avg`, `StdDev`, and `Variance` crash with `filter` argument (#30542).
- Fixed a regression in Django 2.2.2 where auto-reloader crashes with `AttributeError`, e.g. when using `ipdb` (#30588).
