CVE-2026-88983 · Severity: medium · CVSS 5 · Published 2026-11-05

Kubeflow Pipelines is a machine learning workflow platform that allows authenticated users to define and execute data processing pipelines. An authenticated attacker with pipeline creation permissions can supply arbitrary URLs that the API server will fetch, potentially probing internal services and gaining status-code information about private network resources. This provides reconnaissance capabilities for attackers already inside the cluster.

Technologies: github.com/kubeflow/pipelines (Go), Kubeflow Pipelines. Vendors: Go, Kubeflow.

```

Technical details

The vulnerability is a server-side request forgery (SSRF) in the pipeline and pipeline-version creation API endpoints. An authenticated caller can inject a user-controlled pipelineURL parameter that the API server fetches without destination validation. The attacker can observe HTTP status codes from requests to internal services, providing a limited oracle for network reconnaissance; however, response body disclosure and credential theft are not established as practical attack outcomes.

Affected products
