November 5, 2025

Django 5.1.14 fixes one security issue with severity “high” and one security issue with severity “moderate” in 5.1.13.

## 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.
