CVE-2019-10173: Deserialization of Untrusted Data and Code Injection in xstream

July 26, 2019 (updated February 24, 2026)

It was found that xstream API version 1.4.10 before 1.4.11 introduced a regression for a previous deserialization flaw. If the security framework has not been initialized, it may allow a remote attacker to run arbitrary shell commands when unmarshalling XML or any supported format. e.g. JSON. (regression of CVE-2013-7285)
