Description

 deserialize arbitrary types defined in Jenkins core or plugins from an attacker-controlled `config.xml`
 submission in a way that allows them to handle HTTP requests afterwards. This can be used to impersonate
 any user and send HTTP requests on their behalf, up to and including use of the Script Console to run
 arbitrary code, or to read arbitrary files from the Jenkins controller. (CVE-2026-53435)
