Inefficient Algorithmic Complexity
CVE-2025-64460
Summary
An issue was discovered in 6.x prior to 6.0, 5.2 prior to 5.2.9, 5.1 prior to 5.1.15, and 4.2 prior to 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.

CWE-407 - Inefficient Algorithmic Complexity
An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.
