DescriptionCVE.org

GoCD is a continuous deliver server. Prior to 26.1.0, GoCD can return unmasked credentials that administrators stored in the userinfo portion of source control material URLs through several read-only APIs available to regular authenticated users. Although GoCD recommends dedicated username and password fields or secret-management plugins, legacy configuration permits credentials in material URLs, and not every mixed-use API consistently applies URL masking for every material type. An authenticated user with access to an affected pipeline can obtain credentials embedded in its material URL, while dedicated password fields remain encrypted and are not exposed by this issue. This issue is fixed in version 26.1.0.

AnalysisAI

Authenticated, low-privileged users of GoCD before 26.1.0 can retrieve source-control credentials in cleartext from several read-only pipeline and material APIs whose responses fail to mask the userinfo portion of material URLs. Exposure is narrow: it only affects legacy configurations where an administrator embedded a username and password directly in a material URL, while credentials held in GoCD's dedicated password fields or secret-management plugins stay encrypted and are not disclosed by this issue. …
