Spinnaker vulnerabilities

Spinnaker prior to versions 2026.1.1, 2026.0.3, 2025.4.4, and 2025.3.4 contains a vulnerability in Kustomize bake operations that allows unsafe YAML tag processing in rosco manifests. This can lead to remote code execution on rosco pods when performing Kustomize bakes.

A vulnerability in Spinnaker allows remote code execution through unsafe YAML processing when using CloudFormation or CloudFoundry. The use of a non-safe constructor enables arbitrary Java class loading, leading to remote code execution.

Spinnaker versions prior to 2025.1.6, 2025.2.3, and 2025.3.0 are vulnerable to server-side request forgery (SSRF). The flaw allows users to fetch data from a remote URL, which can then be injected into Spinnaker pipelines via Helm or other methods, potentially exposing authentication data such as GitHub auth headers or AWS Metadata information.

Spinnaker, an open source multi-cloud continuous delivery platform, has a logging issue where GitHub status is always logged in full. This may lead to the exposure of GitHub tokens in the logging system.
