GHSA-6c7v-2f49-8h26 Django Incorrect HTTP detection with reverse-proxy connecting via HTTPS

• PyPI Django: >= 2.1, < 2.1.10 → fixed in 2.1.10 • PyPI Django: >= 2.2, < 2.2.3 → fixed in 2.2.3 • PyPI Django: >= 1.11, < 1.11.22 → fixed in 1.11.22

An issue was discovered in Django 1.11 before 1.11.22, 2.1 before 2.1.10, and 2.2 before 2.2.3. An HTTP request is not redirected to HTTPS when the SECURE_PROXY_SSL_HEADER and SECURE_SSL_REDIRECT settings are used, and the proxy connects to Django via HTTPS. In other words, django.http.HttpRequest.scheme has incorrect behavior when a client uses HTTP.
