CVE-2020-2192Network attack vector

Agent label modification via CSRF-enabled GET endpoints

Published Jun 3, 2020 · Updated Aug 4, 2024

Cross-site request forgery in Jenkins Swarm Plugin 3.20 and earlier allows remote authenticated users to alter labels on any agent. The doAddSlaveLabels and doRemoveSlaveLabels endpoints accept state-changing requests without enforcing POST, allowing forged requests to reach label updates. Agent/Create permission is sufficient to obtain the global Swarm secret required by the endpoints; successful requests alter agent scheduling metadata.
