XStream is a Java library to serialize objects to XML and back again. In
XStream before version 1.4.16, there is vulnerability which may allow a
remote attacker to allocate 100% CPU time on the target system depending on
CPU type or parallel execution of such a payload resulting in a denial of
service only by manipulating the processed input stream. 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.
