Short explanation
Prior to version 2.18.0, Kubeflow Pipelines volume artifact handler for GET /artifacts/get?source=volume contains a path traversal vulnerability. This can lead to arbitrary file read when deployments have authentication disabled.
It matters because unauthenticated deployments require no credentials to access sensitive files via path traversal.
What should be done?
- Upgrade to version 2.18.0
- Follow vendor advisory guidelines
Chain of evidence and sources
Kubeflow Pipelines 2.18.0 öncesi sürümlerde volüm yapısı işleyicisi yol atlatma barındırmaktadır.
Kimlik doğrulaması kapalı olan dağıtımlarda uygulama kimlik bilgisi gerekmemektedir.
Show the technical text from the sources
Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.18.0, the volume artifact handler for GET /artifacts/get?source=volume did not confine a caller-supplied file path to the selected volume. A caller who can reach the route and identify an existing mounted volume can use path traversal to read files outside that volume when the artifact-serving process can read them. The frontend pod serves the request when artifact proxying is disabled, while the selected namespace's artifact-service pod serves it when proxying is enabled. A deployment with authentication disabled requires no application credentials; in multi-user deployments, the caller ordinarily must be authorized for the supplied namespace. This issue is fixed in version 2.18.0.
