Description

Spinnaker is an open source, multi-cloud continuous delivery platform. In versions prior to 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2, a bad actor can execute arbitrary commands very simply on the clouddriver pods. This can expose credentials, remove files, or inject resources easily. Versions 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2 contain a patch. As a workaround, disable the gitrepo artifact types.
