XStream is an open source java library to serialize objects to XML and back
again. Versions prior to 1.4.19 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. XStream 1.4.19 monitors and
accumulates the time it takes to add elements to collections and throws an
exception if a set threshold is exceeded. Users are advised to upgrade as
soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to
prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a
workaround if an upgrade is not possible.
