Security readout for executives and security teams

Jenkins instances using Kubernetes CLI Plugin 1.10.0 or earlier may expose Jenkins credential IDs to any user who already has Overall/Read access. This does not disclose credential secret values in the provided sources, but credential IDs can help attackers map sensitive assets and support later attacks. Exposure is limited to Jenkins environments that installed Kubernetes CLI Plugin 1.10.0 or earlier and grant Overall/Read to users who should not see credential metadata. Treat as a near-term Jenkins hardening item, especially where many users have read access. It is not presented as actively exploited, but it can expose credential metadata in a CI/CD control plane. Mitigation focus: Inventory Jenkins installations using Kubernetes CLI Plugin.; Identify any plugin version at or below 1.10.0.; Check the Jenkins advisory for the fixed version and upgrade path..
