GHSA-34wx-x2w9-vqm3DoS vulnerability in bundled XStream library in Jenkins Core2022-02-10ghsa · osvUS
Jenkins 2.333 and earlier, LTS 2.319.2 and earlier is affected by the XStream library’s vulnerability [CVE-2021-43859](https://x-stream.github.io/CVE-2021-43859.html). 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).
