Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jenkins core (org.jenkins-ci.main:jenkins-core) versions 2.500 up to but not including 2.504, and versions before 2.492.3, are affected. An attacker who holds the Computer/Create permission but lacks Computer/Extended Read can copy an agent through an HTTP endpoint that skips the permission check, which gives them access to that agent's configuration. Upgrade to Jenkins 2.504 or LTS 2.492.3, where copying an agent requires Computer/Extended Read.
