XStream is vulnerable to an Arbitrary Code Execution attack

XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to load and execute arbitrary code from a remote host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.

XStream 代码问题漏洞

XStream是XStream（Xstream）团队的一个轻量级的、简单易用的开源Java类库，它主要用于将对象序列化成XML（JSON）或反序列化为对象。 XStream 1.4.17及之前版本存在代码问题漏洞，远程攻击者可以通过操纵处理后的输入流，从远程主机加载和执行任意代码。
