XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is a vulnerability which may allow a remote attacker to load and execute arbitrary code from a remote host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16.

- →The vulnerability involves unsafe deserialization of sun.swing.SwingLazyValue via XStream; detect attempts to deserialize this class in XStream-processed XML input streams ↗
- →Flag XStream versions prior to 1.4.16 in software inventory; exploitation requires the default blacklist security framework to be in use rather than a whitelist ↗
- ·Users who configured XStream's security framework with a whitelist limited to the minimal required types are NOT affected by this vulnerability ↗
- ·OpenShift Container Platform Jenkins packages are not affected due to JEP-200 and JEP-228 protections applied to the bundled XStream library ↗
- ·Red Hat JBoss AMQ 6 distributes affected XStream versions but is not susceptible because the XStream security framework with an allowlist is in place ↗

## Abstract
Java (de)serialization is prone to causing security-critical vulnerabilities that attackers can invoke existing methods (gadgets) on the application's classpath to construct a gadget chain to perform malicious behaviors. Several techniques have been proposed to statically identify suspicious gadget chains and dynamically g
