SCA: security update for com.thoughtworks.xstream:xstream (GHSA-hvv8-336g-rx3m)

critical Tenable Self-Hosted Container Security Plugin ID 415961

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16,
 there is a vulnerability where the processed stream at unmarshalling time contains type information to
 recreate the formerly written objects. XStream creates therefore new instances based on these type
 information. An attacker can manipulate the processed input stream and replace or inject objects, that
 result in a server-side forgery request. 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.
 (CVE-2021-21342)
