Affected packages
• PyPI Django: >= 5.2a1, < 5.2.9 → fixed in 5.2.9
• PyPI Django: >= 5.1a1, < 5.1.15 → fixed in 5.1.15
• PyPI Django: >= 4.2a1, < 4.2.27 → fixed in 4.2.27
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.
