7.2 highEPSS 0.3%Fix available

High (7.2) in kubeflow pipelines. EPSS 0.3% estimated probability of exploitation activity in the next 30 days. Fixed in github.com/kubeflow/pipelines 0.0.0-20260420170029-186dd1f3b040.

On this page
Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.16.1, the multi-user API server treats the empty namespace used by shared or global pipelines as an authorization exception for modification and deletion operations. An authenticated user can modify or delete shared pipeline definitions and versions without the required Kubernetes RBAC permissions, compromising their integrity and availability. Read-only access to shared pipelines remains intentional, single-user deployments intentionally bypass multi-user checks, and execution of a modified pipeline is a conditional downstream consequence. The separate shared-pipeline multipart upload authorization path is outside this advisory and is not remediated by version 2.16.1. This issue is fixed in version 2.16.1.

Red Hat

Red Hat rates this Important.

Red Hat's statement

This vulnerability is rated as Important because any authenticated user in a multi-tenant environment can bypass access controls to alter or destroy shared pipeline definitions, causing broad integrity and availability impacts across projects. In Red Hat OpenShift AI deployments providing shared Kubeflow Pipelines, the API server fails to enforce authorization checks on global pipeline resources that lack a namespace designation. Consequently, low-privileged users can modify or remove workflows relied upon by other teams without requiring cluster administrator privileges.

Red Hat's mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
