CVE-2026-118758: Kubeflow Pipelines path traversal in GET /artifacts/get volume handler

Source: NVD(opens in a new tab)
Identifier: CVE-2026-118758
Published: October 29, 2026
Record updated: October 29, 2026

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.

Summary

Prior to 2.18.0, the volume artifact handler for GET /artifacts/get?source=volume in Kubeflow Pipelines did not confine a caller-supplied file path to the selected volume. A caller who can reach the route and name an existing mounted volume can use path traversal to read files outside that volume, if the artifact-serving process can read them. With authentication disabled no application credentials are needed; in multi-user deployments the caller ordinarily must be authorized for the supplied namespace.

Mitigation

Fixed in version 2.18.0.
