CVE-2025-64460 · Severity: high · CVSS 7.5 · Published 2025-12-02

Django, a popular web framework for building Python applications, is vulnerable to a denial-of-service attack. An attacker can send a specially crafted XML file to a website using Django's XML processing features, causing the server to consume excessive CPU and memory. This can lead to the website becoming slow or completely unavailable to legitimate users.

  ```


## Technical details

A vulnerability exists in the `django.core.serializers.xml_serializer.getInnerText()` function due to inefficient algorithmic complexity (CWE-407). A remote, unauthenticated attacker can exploit this by submitting specially crafted XML input to be processed by the XML `Deserializer`. Successful exploitation triggers CPU and memory exhaustion, leading to a denial-of-service condition. The issue is fixed in Django versions 5.2.9, 5.1.15, and 4.2.27. Unsupported versions such as 5.0.x and 3.2.x may also be affected but were not evaluated.

## Affected products

- Django Software Foundation Django >= 5.2a1, < 5.2.9; >= 5.1a1, < 5.1.15; >= 4.2a1, < 4.2.27
