An issue was discovered in Django 1.11 before 1.11.21, 2.1 before 2.1.9, and 2.2 before 2.2.2. The clickable Current URL value displayed by the AdminURLFieldWidget displays the provided value without validating it as a safe URL. Thus, an unvalidated value stored in the database, or a value provided as a URL query parameter payload, could result in an clickable JavaScript link.

Affected: Ubuntu:16.04:LTS: python-django, Ubuntu:18.04:LTS: python-django

It was discovered that Django incorrectly handled certain inputs. An attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 18.04 LTS, Ubuntu 18.10 and Ubuntu 19.04. (CVE-2019-12308)

Gavin Wahl discovered that Django incorrectly handled HTTP detection when used behind a reverse-proxy. Client requests made via HTTP would cause incorrect API results and would not be redirected to HTTPS, contrary to expectations. (CVE-2019-12781)
