Summary
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.
Risk Assessment
The organization may face credential and authentication data exposure, and attackers could access internal Spinnaker APIs. The risk is particularly high when artifact providers allowing user-supplied URLs (e.g., GitHub, BitBucket, GitLab, HTTP) are enabled alongside systems that consume their output (e.g., Rosco Helm).
Recommendation
Upgrade Spinnaker to version 2025.1.6, 2025.2.3, or 2025.3.0. If upgrading is not possible, disable HTTP account types that allow user input of URLs or use OPA policies to restrict pipelines from accessing or saving invalid URLs.
Other vulnerabilities in Spinnaker
See all- CVE-2026-55175High
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.
- CVE-2026-44795High
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.
- CVE-2023-39348Medium
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.
Original NVD description (English source)
Spinnaker is an open source, multi-cloud continuous delivery platform. Versions prior to 2025.1.6, 2025.2.3, and 2025.3.0 are vulnerable to server-side request forgery. The primary impact is allowing users to fetch data from a remote URL. This data can be then injected into spinnaker pipelines via helm or other methods to extract things LIKE idmsv1 authentication data. This also includes calling internal spinnaker API's via a get and similar endpoints. Further, depending upon the artifact in question, auth data may be exposed to arbitrary endpoints (e.g. GitHub auth headers) leading to credentials exposure. To trigger this, a spinnaker installation MUST have two things. The first is an artifact enabled that allows user input. This includes GitHub file artifacts, BitBucket, GitLab, HTTP artifacts and similar artifact providers. JUST enabling the http artifact provider will add a "no-auth" http provider that could be used to extract link local data (e.g. AWS Metadata information). The second is a system that can consume the output of these artifacts. e.g. Rosco helm can use this to fetch values data. K8s account manifests if the API returns JSON can be used to inject that data into the pipeline itself though the pipeline would fail. This vulnerability is fixed in versions 2025.1.6, 2025.2.3, and 2025.3.0. As a workaround, disable HTTP account types that allow user input of a given URL. This is probably not feasible in most cases. Git, Docker and other artifact account types with explicit URL configurations bypass this limitation and should be safe as they limit artifact URL loading. Alternatively, use one of the various vendors which provide OPA policies to restrict pipelines from accessing or saving a pipeline with invalid URLs.
