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.
