[dependabot-preview]

Bumps django from 1.11.18 to 1.11.22. This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Moderate severity vulnerability that affects django
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 versions: >= 1.11.0, < 1.11.21

Moderate severity vulnerability that affects django
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.

Affected versions: >= 1.11.0, < 1.11.22

Memory exhaustion in django.utils.numberformat.format()
If django.utils.numberformat.format() -- used by contrib.admin as well as the the floatformat, filesizeformat, and intcomma templates filters -- received a Decimal with a large number of digits or a large exponent, it could lead to significant memory usage due to a call to '{:f}'.format().

Affected versions: >= 1.11.0, < 1.11.19; >= 2.0.0, < 2.0.11; >= 2.1.0, < 2.1.6

Sourced from The GitHub Security Advisory Database.

Affected versions: < 1.11.19
