This vulnerability has a CVSS 3.1 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

GoCD is a continuous deliver server. Prior to 26.1.0, the internal GoCD UI /jobStatus.json API does not validate that a requested server-assigned job ID belongs to the pipeline and stage named in the request. An authenticated user can guess job IDs and retrieve status for jobs in pipelines the user cannot otherwise view, including job names, state, progress timestamps, assigned agent IP addresses and UUIDs, and associated stages and pipelines. The response does not expose console output, artifacts, commands, variables, or configuration. This issue is fixed in version 26.1.0.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
