Workaround
=========

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.
