Summary
=======

The package python-django before version 3.0.7-1 is vulnerable to
multiple issues including cross-site scripting and information
disclosure.

Resolution
==========

Upgrade to 3.0.7-1.

# pacman -Syu "python-django>=3.0.7-1"

The problems have been fixed upstream in version 3.0.7.

Workaround
==========

None.

Description
===========

- CVE-2020-13254 (information disclosure)

An information disclosure issue has been found in Django before 3.0.7,
via malformed memcached keys. In cases where a memcached backend does
not perform key validation, passing malformed cache keys could result
in a key collision, and potential data leakage. In order to avoid this
vulnerability, key validation is added to the memcached cache backends.

- CVE-2020-13596 (cross-site scripting)

A possible XSS has been found in Django before 3.0.7, via admin
ForeignKeyRawIdWidget. Query parameters for the admin
ForeignKeyRawIdWidget were not properly URL encoded, posing an XSS
attack vector.

Impact
======

A remote attacker can leak data through malformed cache keys. An
authenticated user could execute javascript through an admin widget.
