Django 2.1.9 fixes security issues in 2.1.8.

CVE-2019-12308: AdminURLFieldWidget XSS

The clickable “Current URL” link generated by AdminURLFieldWidget displayed 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.

AdminURLFieldWidget now validates the provided value using URLValidator before displaying the clickable link. You may customize the validator by passing a validator_class kwarg to AdminURLFieldWidget.__init__(), e.g. when using formfield_overrides.

Patched bundled jQuery for CVE-2019-11358: Prototype pollution

jQuery before 3.4.0, mishandles jQuery.extend(true, {}, ...) because of Object.prototype pollution. If an unsanitized source object contained an enumerable __proto__ property, it could extend the native Object.prototype.

The bundled version of jQuery used by the Django admin has been patched to allow for the select2 library’s use of jQuery.extend().
