The vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream with a Java runtime version 14 to 8. 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 1.4.18.
See workarounds for the different versions covering all CVEs.
