Vulnerability description
DayBreach CVE AI Research
CVE-2021-39145 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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.
