{"id":"CVE-2026-88986","published":"2026-11-05T22:18:54.743","lastModified":"2026-11-05T22:18:54.743","description":"Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.15.0, the frontend routes /pipeline/k8s/pod and /pipeline/k8s/pod/events use frontend/server/k8s-helper.ts to include untrusted podname and podnamespace query values and backend error details in HTML-capable error responses. An unauthenticated attacker can craft a link that executes JavaScript in the frontend origin when a user who satisfies the deployment's authentication and route-access requirements follows it and reaches an affected response. Cookie disclosure depends on cookie attributes, and server-side code execution or availability impact is not established. This issue is fixed in version 2.15.0.","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/kubeflow/pipelines/commit/fedc25e3f7251933d4a37b964bc3e8176beea28e","tags":[]},{"url":"https://github.com/kubeflow/pipelines/pull/12295","tags":[]},{"url":"https://github.com/kubeflow/pipelines/releases/tag/2.15.0","tags":[]},{"url":"https://github.com/kubeflow/pipelines/security/advisories/GHSA-g3qx-frcg-j979","tags":[]}],"exploitRefs":[{"url":"https://github.com/kubeflow/pipelines/commit/fedc25e3f7251933d4a37b964bc3e8176beea28e","tags":[]},{"url":"https://github.com/kubeflow/pipelines/pull/12295","tags":[]},{"url":"https://github.com/kubeflow/pipelines/releases/tag/2.15.0","tags":[]},{"url":"https://github.com/kubeflow/pipelines/security/advisories/GHSA-g3qx-frcg-j979","tags":[]}],"hasPoc":true,"ai":null}
