Short explanation
An authorization flaw in the Kubeflow Pipelines API server allows unauthenticated users to read pod execution logs cross-tenant.
This vulnerability can lead to unauthorized parties reading sensitive workload data and credentials across the network.
What should be done?
- Upgrade Kubeflow Pipelines to version 2.18.0 or later
- Implement external authentication gates
- Limit reachability using network policies
Chain of evidence and sources
Kubeflow Pipelines 2.18.0 öncesi sürümlerde, günlük akışı uç noktası ad alanı yetkilendirmesini atlamaktadır.
Bu güvenlik açığı 2.18.0 sürümünde giderilmiştir.
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 API server's GET /apis/v1alpha1/runs/{run_id}/nodes/{node_id}/log handler retrieved logs without authorizing the caller against the selected run. A caller who can reach the backend and knows a victim run ID and suitable pod or node identifier can read live or archived logs with the API server's permissions. For live logs, the caller-controlled node ID was also accepted as a pod name without verifying that the pod belonged to the requested run, allowing a known run ID to select the namespace of an unrelated pod and read its main container logs. The handler does not authenticate requests itself, although an external authentication gate or network policy can limit reachability. Exposed logs can contain sensitive workload data or credentials. This issue is fixed in version 2.18.0.
