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
|
|
|
|
|
:class:`~django.core.validators.URLValidator` before displaying the clickable
|

|
|
|
link. You may customize the validator by passing a ``validator_class`` kwarg to
|
2019-05-23 12:06:34 +02:00
|
|
|
``AdminURLFieldWidget.__init__()``, e.g. when using
|
|
|
|
|
:attr:`~django.contrib.admin.ModelAdmin.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()``.
