CVE-2025-64458: Potential denial-of-service vulnerability in ``HttpResponseRedirect`` and ``HttpResponsePermanentRedirect`` on Windows
|
|
======================================================================================================================================
|
|
|
|
Python's :func:`NFKC normalization <python:unicodedata.normalize>` is slow on
|
|
Windows. As a consequence, :class:`~django.http.HttpResponseRedirect`,
|
|
:class:`~django.http.HttpResponsePermanentRedirect`, and the shortcut
|
|
:func:`redirect() <django.shortcuts.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`).
