Vulnerability from github
Impact
The vulnerability 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.
Patches
XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.
Workarounds
See workarounds for the different versions covering all CVEs.
References
