Django 3.0.7 リリースノート

June 3, 2020

Django 3.0.7 では、3.0.6 の2つのセキュリティの問題といくつかのバグを修正しました。

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.
