Django 2.2.13 release notes

June 3, 2020

Django 2.2.13 fixes two security issues and a regression in 2.2.12.

CVE-2020-13254: Potential data leakage 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: Possible XSS via admin ForeignKeyRawIdWidget

Query parameters for the admin ForeignKeyRawIdWidget were not properly URL encoded, posing an XSS attack vector. ForeignKeyRawIdWidget now ensures query parameters are correctly URL encoded.


  • Fixed a regression in Django 2.2.12 that affected translation loading for apps providing translations for territorial language variants as well as a generic language, where the project has different plural equations for the language (#31570).
  • Tracking a jQuery security release, upgraded the version of jQuery used by the admin from 3.3.1 to 3.5.1.
