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.","state":0,"publishedAt":"2026-10-29T16:12:42.138+00:00","modifiedAt":"2026-10-29T16:12:42.138+00:00","affected":[{"ecosystem":"Vendor product","name":"pipelines","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"kubeflow\",\n                    \"product\": \"pipelines\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.18.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://github.com/kubeflow/pipelines/security/advisories/GHSA-2fg9-fx2f-439r","https://github.com/kubeflow/pipelines/pull/13677","https://github.com/kubeflow/pipelines/commit/4d9bc5ab12b67efedb3923ef428a399cb445cf5f","https://github.com/kubeflow/pipelines/blob/2.18.0/docs/operator-guides/upgrade-2.18.md#custom-storage-configuration-and-rollout","https://github.com/kubeflow/pipelines/releases/tag/2.18.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-118758","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-118758","identifiers":["CVE-2026-118758"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
