Django Inefficient Algorithmic Complexity Vulnerability - CVE-2025-64460

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.
