# Django 4.2.17 リリースノート

*2024年12月4日*

Django 4.2.17 では 4.2.16 におけるセキュリティの問題のうち 深刻度 "high" 1件と深刻度 "moderate" 1件を修正しました。

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

[`strip_tags()`](/ja/5.2/ref/utils/#django.utils.html.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`](/ja/5.2/ref/templates/builtins/#std-templatefilter-striptags) template filter, which was thus also vulnerable.

`strip_tags()` now has an upper limit of recursive calls to `HTMLParser`
before raising a [`SuspiciousOperation`](/ja/5.2/ref/exceptions/#django.core.exceptions.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()`](/ja/5.2/ref/utils/#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`](/ja/5.2/topics/db/queries/#std-fieldlookup-jsonfield.has_key) lookup through
the `__` syntax are unaffected.
