Description
Jenkins 2.587 and earlier, LTS 2.580.1 and earlier converts the launch commands in older agent configurations into launchers provided by the Command Agent Launcher Plugin without checking whether they have been approved by an administrator, allowing attackers with Agent/Configure permission to execute arbitrary code in the context of the Jenkins controller JVM.
