Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Insecure Deserialization: XStream.fromXML deserializes untrusted XML/JSON without a comprehensive type allowlist; the denyTypes workaround was incomplete and required an upstream library upgrade to fully address CVE-2017-7957.

Deserialization Vulnerability Fix: Relying on a manual denyTypes list for void/Void classes was insufficient; the official fix in XStream 1.4.10 was required to close the vulnerability.

Denial of Service: The deserializer lacked end-of-input checks, allowing crafted input to cause an infinite loop and exhaust resources.
