# Catatan terbitan Django 5.2.9

December 2, 2025

Django 5.2.9 fixes one security issue with severity "high", one security issue with severity "moderate", and several bugs in 5.2.8.

## CVE-2025-13372: Potential SQL injection in `FilteredRelation` column aliases on PostgreSQL

`FilteredRelation` was subject to SQL injection in column aliases, using a suitably crafted dictionary, with dictionary expansion, as the `**kwargs` passed to `QuerySet.annotate()` or `QuerySet.alias()` on PostgreSQL.

## CVE-2025-64460: Potential denial-of-service vulnerability in XML `Deserializer`

XML Serialization was subject to a potential denial-of-service attack due to quadratic time complexity when deserializing crafted documents containing many nested invalid elements. The internal helper `django.core.serializers.xml_serializer.getInnerText()` previously accumulated inner text inefficiently during recursion. It now collects text per element, avoiding excessive resource usage.

## Perbaikan kesalahan

- Fixed a bug in Django 5.2 where `django.utils.feedgenerator.Stylesheet.__str__()` did not escape the `url`, `mimetype`, and `media` attributes, potentially leading to invalid XML markup (#36733).

- Fixed a bug in Django 5.2 on PostgreSQL where `bulk_create()` did not apply a field's custom query placeholders (#36748).

- Fixed a regression in Django 5.2.2 that caused a crash when using aggregate functions with an empty `Q` filter over a queryset with annotations (#36751).

- Fixed a regression in Django 5.2.8 where `DisallowedRedirect` was raised by `HttpResponseRedirect` and `HttpResponsePermanentRedirect` for URLs longer than 2048 characters. The limit is now 16384 characters (#36743).

- Fixed a crash on Python 3.14+ that prevented template tag functions from being registered when their type annotations required deferred evaluation (#36712).
