Description

Jenkins 2.333 and earlier, LTS 2.319.2 and earlier is affected by the XStream library’s vulnerability CVE-2021-43859. This library is used by Jenkins to serialize and deserialize various XML files, like global and job `config.xml`, `build.xml`, and numerous others. This allows attackers able to submit crafted XML files to Jenkins to be parsed as configuration, e.g. through the `POST config.xml` API, to cause a denial of service (DoS).
