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, +:attr:`django.http.HttpRequest.scheme` would incorrectly detect client +requests made via HTTP as using HTTPS. This entails incorrect results for +:meth:`~django.http.HttpRequest.is_secure`, and +:meth:`~django.http.HttpRequest.build_absolute_uri`, and that HTTP +requests would not be redirected to HTTPS in accordance with +:setting:`SECURE_SSL_REDIRECT`. + +``HttpRequest.scheme`` now respects :setting:`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``.
