CVE-2026-55625

Overview

CVE-2026-55625 affects GoCD servers from 16.1.0 to 26.1.0, allowing a pipeline‑group administrator to test source control connections for pipelines outside their authorized group. This can expose credentials and external secrets, potentially compromising the confidentiality of the CI/CD environment. The issue is fixed in version 26.1.0.

Description

GoCD is a continuous deliver server. From 16.1.0 until 26.1.0, the internal material connection test APIs at /go/api/admin/internal/material_test and /go/api/internal/config_repos/*/material_test accept an arbitrary existing pipeline and pipeline-group context without sufficient validation. A pipeline group administrator can invoke Test Connection for source control materials outside the administrator's authorized pipeline group or configuration repository and potentially use credentials from those materials. For GoCD 20.6.0 and later, the test context can also resolve external secrets managed by secret-management plugins, including global reusable secrets with separate permissions. This issue is fixed in version 26.1.0.

Impact

Confidentiality: credentials and secrets may be exposed to unauthorized administrators. Integrity: risk of unauthorized configuration changes. Availability: minimal impact. Impacted parties: GoCD administrators and DevOps teams.

Remediation

Apply the official patch by upgrading to GoCD 26.1.0 or later. Restrict pipeline‑group administrator permissions to only the pipelines they manage. Review and tighten secret‑management plugin permissions to limit global reusable secret access.

Risk context

Medium severity with no EPSS data; patching is recommended promptly to mitigate potential credential exposure.
