Vulnerability Title
Denial of Service by injecting highly recursive collections or maps in XStream
Vulnerability Description
XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible.

Vulnerability Title
XStream 资源管理错误漏洞
Vulnerability Description
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 存在资源管理错误漏洞，该漏洞允许远程攻击者可利用该漏洞根据CPU类型或此类负载的并行执行在目标系统上分配100%的CPU时间，导致仅通过操作已处理的输入流来拒绝服务。XStream 1.4.19监视并累积向集合添加元素所需的时间，并在超过设置的阈值时抛出异常。建议用户尽快升级。无法升级的用户可以设置NO REFERENCE模式以防止递
