Vulnerability Analysis
XStream is vulnerable to a Remote Command Execution attack
CVE-2021-39144
XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream.
