# 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.

## Poprawki błędów

- 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](https://code.djangoproject.com/ticket/31570)).
- Tracking a jQuery security release, upgraded the version of jQuery used by
  the admin from 3.3.1 to 3.5.1.
