Thanks Gavin Wahl for reporting this issue.

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 .
