Spinnaker is an open source, multi-cloud continuous delivery platform. Prior to versions 2026.1.1, 2026.0.3, 2025.4.4, and 2025.3.4 on their respective release lines, Kustomize bake operations allow unsafe YAML tag processing in rosco manifests. This can lead to remote code execution on rosco pods when performing Kustomize bakes. This issue is fixed in versions 2026.1.1, 2026.0.3, 2025.4.4, and 2025.3.4.

GHSA-p68j-q7hf-3qcpSpinnaker: Improper yaml processing on kustomize bake operations2026-08-28ghsa · osvUS
### Impact Kustomize bake operations allow unsafe tag processing. This can lead to RCE type exploits on the rosco pods when doing kustomize bakes. This ONLY is possible when using Kustomize. The simple solution is to block kustomize operations and instead use another provider. ### Workarounds Disable kustomize bakes
