CVE-2021-21343

Description

XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is a vulnerability where the processed stream at unmarshalling time contains type information to recreate the formerly written objects. XStream creates therefore new instances based on these type information. An attacker can manipulate the processed input stream and replace or inject objects, that result in the deletion of a file on the local host. No user is affected, who followed the recommendation to setup XStreams security framework with a whitelist limited to the minimal required types. If you rely on XStreams default blacklist of the Security Framework, you will have to use at least version 1.4.16.
