How to fix?

Upgrade com.thoughtworks.xstream:xstream to version 1.4.15 or higher.


com.thoughtworks.xstream:xstream is a simple library to serialize objects to XML and back again.

Affected versions of this package are vulnerable to Server-Side Request Forgery (SSRF). A remote attacker can request data from internal resources that are not publicly available by manipulating the processed input stream.

Note: This vulnerability does not exist running Java 15 or higher, and is only relevant when using XStream's default blacklist.
