Prior to 2.17.0, the API server's pipeline and pipeline-version creation paths fetch a caller-supplied pipelineURL without restricting the destination. An authenticated caller with permission to create a pipeline or pipeline version can make requests from the API server to internal services and observe a limited status-code oracle. Arbitrary response-body disclosure, credential theft, and integrity or availability impact are not established. This issue is fixed in version 2.17.0.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":5,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","version":"3.1"}],"modifiedAt":1793915933008,"publishedAt":1793915933008,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/kubeflow/pipelines/security/advisories/GHSA-f7vj-6669-qvv4"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/kubeflow/pipelines/pull/12750"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/kubeflow/pipelines/commit/504d7797c1e061327ddb2bcb8bc1c5dd4940cfc3"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/kubeflow/pipelines/releases/tag/2.17.0"}],"remediation":[],"revision":"f9da2e2789cf6b4ca50d7e7fdc7520c3cfc7e931964e73bf15e9ae7a6aefc530","sources":[{"modifiedAt":1793915933008,"name":"CNA: GitHub_M","retrievedAt":1793917178451,"url":"https://www.cve.org/CVERecord?id=CVE-2026-88983"}],"ssvc":null,"status":"published","title":"Kubeflow Pipelines — API server fetches a caller-supplied pipelineURL without host validation","updatedAt":1793917178451}
