Django 5.1.15 release notes

December 2, 2025

Django 5.1.15 fixes one security issue with severity "high", one security issue with severity "moderate", and one bug in 5.1.14.

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.

漏洞修复

• Fixed a regression in Django 5.1.14 where DisallowedRedirect was raised by HttpResponseRedirect and HttpResponsePermanentRedirect for URLs longer than 2048 characters. The limit is now 16384 characters (#36743).
