# Django 5.2.8 release notes

November 5, 2025

Django 5.2.8 fixes one security issue with severity „high”, one security issue with severity „moderate”, and several bugs in 5.2.7. It also adds compatibility with Python 3.14.

## CVE-2025-64458: Potential denial-of-service vulnerability in `HttpResponseRedirect` and `HttpResponsePermanentRedirect` on Windows

Python’s `NFKC normalization` is slow on Windows. As a consequence, `HttpResponseRedirect`, `HttpResponsePermanentRedirect`, and the shortcut `redirect()` were subject to a potential denial-of-service attack via certain inputs with a very large number of Unicode characters (follow up to CVE 2025-27556).

## CVE-2025-64459: Potential SQL injection via `_connector` keyword argument

`QuerySet.filter()`, `exclude()`, `get()`, and `Q` were subject to SQL injection using a suitably crafted dictionary, with dictionary expansion, as the `_connector` argument.

## Poprawki błędów

- Added compatibility for `oracledb` 3.4.0 (#36646).

- Fixed a bug in Django 5.2 where `QuerySet.first()` and `QuerySet.last()` raised an error on querysets performing aggregation that selected all fields of a composite primary key (#36648).

- Fixed a bug in Django 5.2 where proxy models having a `CompositePrimaryKey` incorrectly raised a `models.E042` system check error (#36704).
