GoCD is vulnerable to authorization bypass via material connection test APIs

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
