GHSA-f8cc-g7j8-xxpm XStream can cause a Denial of Service by injecting deeply nested objects raising a stack overflow

• Maven com.thoughtworks.xstream:xstream: < 1.4.20 → fixed in 1.4.20

Impact The vulnerability may allow a remote attacker to terminate the application with a stack overflow error resulting in a denial of service only by manipulating the processed input stream. Patches XStream 1.4.20 handles the stack overflow and raises an InputManipulationException instead. Workarounds The only solution is to catch the StackOverflowError in the client code calling XStream. References See full information about the nature of the vulnerability and the steps to reproduce it in XStream's documentation for CVE-2022-40151.
