CVE-2021-39152 Information

Description

XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream with a Java runtime version 14 to 8. No user is affected who followed the recommendation to setup XStream’s security framework with a whitelist limited to the minimal required types. If you rely on XStream’s default blacklist of the Security Framework you will have to use at least version 1.4.18.
