Summary
Kubeflow Pipelines is affected by a flaw in its API server, which fetches a caller-supplied pipeline URL without restricting the destination. An attacker who can log in with permission to create pipelines can remotely make the server send requests to internal services and learn limited information from the status codes returned, though response contents, credentials, and integrity or availability are not affected.

Read the original description
Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.17.0, the API server's pipeline and pipeline-version creation paths fetch a caller-supplied pipelineURL without restricting the destination. An authenticated caller with permission to create a pipeline or pipeline version can make requests from the API server to internal services and observe a limited status-code oracle. Arbitrary response-body disclosure, credential theft, and integrity or availability impact are not established. This issue is fixed in version 2.17.0.
