What is CVE-2025-64460?

An issue in the Django XML deserialization process can lead to a denial-of-service attack due to algorithmic complexity in handling specially crafted XML input. The affected versions of Django, including 5.2, 5.1, and 4.2, may experience CPU and memory exhaustion when processing such input through the XML Deserializer. Earlier versions like 5.0.x, 4.1.x, and 3.2.x are not officially evaluated but could also be at risk. This vulnerability emphasizes the importance of maintaining updated software to safeguard against potential exploits.
