Auth bypass in Gocd

CVE-2026-52744

GoCD is a continuous deliver server. From 20.2.0 until 26.1.0, the internal GoCD UI fetch-artifact auto-suggestion API at /go/api/internal/pipelines/**/upstream does not adequately authorize access to upstream dependency data. An authenticated user can retrieve inter-pipeline dependency hierarchy details and user-defined pipeline, stage, job, and artifact plugin reference names that the user cannot otherwise view in the UI. The endpoint is read-only and does not permit modification of pipeline data. This issue is fixed in version 26.1.0.
