{"affected":[{"product":"pipelines","source":"CNA: GitHub_M","vendor":"kubeflow","versions":[{"status":"affected","version":"< 2.18.0"}]}],"cveId":"CVE-2026-88981","cwes":["CWE-918"],"description":"Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.18.0, the frontend artifact download path for source=s3 or source=minio accepts providerInfo.Params.endpoint, and the archived pod-log path accepts S3-compatible endpoint metadata from workflow status, without requiring those endpoints to match operator-controlled storage configuration. In the shipped authorization-disabled standalone configuration, an unauthenticated caller can make the shared ml-pipeline-ui pod connect to arbitrary reachable hosts and return response data; requests may also reveal an access-key identifier when signed with configured object-store credentials. Multi-user secret-backed metadata remains restricted to the server namespace. This issue is fixed in version 2.18.0.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":8.6,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1793917290033,"publishedAt":1793917290033,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/kubeflow/pipelines/security/advisories/GHSA-3pcj-8j5w-jmxq"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/kubeflow/pipelines/pull/14349"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/kubeflow/pipelines/commit/0b77f9b07bfb9860dc90106003bbc3e2fe0e0965"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/kubeflow/pipelines/releases/tag/2.18.0"}],"remediation":[],"revision":"4831dc92570ce969b187dcd8601e8998a38b5aa97df25018acd5fd50969e6c28","sources":[{"modifiedAt":1793917290033,"name":"CNA: GitHub_M","retrievedAt":1793920180133,"url":"https://www.cve.org/CVERecord?id=CVE-2026-88981"}],"ssvc":null,"status":"published","title":"Kubeflow Pipelines: Unauthenticated SSRF through artifact provider endpoints","updatedAt":1793920180133}
