Django 4.0.2 リリースノート

2022年2月1日

Django 4.0.2 では、 4.0.1 における深刻度 "medium" のセキュリティの問題2件と、いくつかのバグを修正しました。また、 Transifex からの最新の文字列翻訳が反映され、ブルガリア語の翻訳が完了しました。

CVE-2022-22818: {% debug %} テンプレート経由の XSS の可能性

The {% debug %} template tag didn't properly encode the current context, posing an XSS attack vector.

In order to avoid this vulnerability, {% debug %} no longer outputs information when the DEBUG setting is False, and it ensures all context variables are correctly escaped when the DEBUG setting is True.

CVE-2022-23833: Denial-of-service possibility in file uploads

Passing certain inputs to multipart forms could result in an infinite loop when parsing files.
