CVE-2025-64460 (GCVE-0-2025-64460)

Vulnerability from cvelistv5 – Published: 2025-12-02 15:15 – Updated: 2025-12-02 21:54

Title

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

Summary

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.

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.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
