NVD Description

Note: Versions mentioned in the description apply only to the upstream libxstream-java package and not the libxstream-java package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

XStream is a simple library to serialize objects to XML and back again. In affected versions this 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.
