Django 5.1.4 リリースノート

2024年12月4日

Django 5.1.4 では、 5.1.3 におけるセキュリティの問題のうち深刻度 "high" 1件、深刻度 "moderate" 1件を含め、いくつかのバグを修正しました。

CVE-2024-53907: strip_tags() における DoS 攻撃の可能性

strip_tags() would be extremely slow to evaluate certain inputs containing large sequences of nested incomplete HTML entities. The strip_tags() method is used to implement the corresponding striptags template filter, which was thus also vulnerable.

strip_tags() now has an upper limit of recursive calls to HTMLParser before raising a SuspiciousOperation exception.

Remember that absolutely NO guarantee is provided about the results of strip_tags() being HTML safe. So NEVER mark safe the result of a strip_tags() call without escaping it first, for example with django.utils.html.escape().

CVE-2024-53908: Potential SQL injection via HasKey(lhs, rhs) on Oracle

Direct usage of the django.db.models.fields.json.HasKey lookup on Oracle was subject to SQL injection if untrusted data was used as a lhs value.

Applications that use the has_key lookup through the __ syntax are unaffected.

バグ修正

  • Fixed a crash in createsuperuser on Python 3.13+ caused by an unhandled OSError when the username could not be determined (#35942).

  • Fixed a regression in Django 5.1 where relational fields were not updated when calling Model.refresh_from_db() on instances with deferred fields (#35950).
