# Django 5.0.10 release notes

December 4, 2024

Django 5.0.10 fixes one security issue with severity „high” and one security issue with severity „moderate” in 5.0.9.

## CVE-2024-53907: Denial-of-service possibility in `strip_tags()`

`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.
