Security readout for executives and security teams
Jenkins Nomad Plugin 0.7.4 and earlier can leave Docker passwords stored unencrypted on the Jenkins controller. The main business risk is credential exposure to anyone who can read controller files, potentially enabling unauthorized Docker registry access. Organizations are exposed if they run Jenkins Nomad Plugin 0.7.4 or earlier and configured Docker passwords in the plugin. Risk is highest where controller filesystem access is shared, weakly controlled, or available through backups and support bundles. Handle during the next security maintenance cycle unless Jenkins controller filesystem access is broadly available. Escalate if Docker credentials protect sensitive images, production registries, or privileged deployment workflows. Mitigation focus: Check Jenkins advisory guidance for fixed versions or vendor-supported remediation.; Upgrade or disable the Nomad Plugin where affected versions are present.; Restrict Jenkins controller filesystem access to essential administrators only..
