Doc Text:
A flaw was found in Kubeflow Pipelines. The API server does not restrict destination addresses when fetching caller-supplied URLs during pipeline or pipeline-version creation. An authenticated user with pipeline creation privileges can exploit this Server-Side Request Forgery (SSRF) vulnerability to initiate requests from the API server to internal network services. By analyzing the returned status codes, an attacker can probe and discover internal network resources.

Description OSIDB Bzimport 2026-11-05 22:42:02 UTC
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.
