XStream is a simple library to serialize objects to XML and back again. In
affected versions this vulnerability may allow a remote attacker to load
and execute arbitrary code from a remote host 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. XStream 1.4.18 uses no longer a
blacklist by default, since it cannot be secured for general purpose.

Notes

Author Note
