CVE-2025-64460

Potential denial-of-service vulnerability in XML serializer text extraction

State: Published
Severity: 7.5 High
Published: Dec 2, 2025
Updated: Dec 2, 2025
Reserved: Nov 4, 2025

Description

An issue was discovered in 5.2 before 5.2.9, 5.1 before 5.1.15, and 4.2 before 4.2.27. Algorithmic complexity in `django.core.serializers.xml_serializer.getInnerText()` allows a remote attacker to cause a potential denial-of-service attack triggering CPU and memory exhaustion via specially crafted XML input processed by the XML `Deserializer`. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Seokchan Yoon for reporting this issue.
