# Django 3.0.7 release notes

June 3, 2020

Django 3.0.7 fixes two security issues and several bugs in 3.0.6.

## 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.
