CVE-2021-21344

Name of the Vulnerable Software and Affected Versions XStream versions prior to 1.4.16

Description The issue is related to the XStream Java library, which is used for serializing objects to XML and back again. It may allow a remote attacker to load and execute arbitrary code from a remote host by manipulating the processed input stream. Users who set up XStream's security framework with a whitelist limited to the minimal required types are not affected.

Recommendations For versions prior to 1.4.16, update to at least version 1.4.16 to resolve the issue. As a temporary workaround, consider setting up XStream's security framework with a whitelist limited to the minimal required types.
