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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.1,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793916512749,"publishedAt":1793916512749,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/kubeflow/pipelines/security/advisories/GHSA-g3qx-frcg-j979"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/kubeflow/pipelines/pull/12295"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/kubeflow/pipelines/commit/fedc25e3f7251933d4a37b964bc3e8176beea28e"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/kubeflow/pipelines/releases/tag/2.15.0"}],"remediation":[],"revision":"89dd3f4a951d421a7193a6f84c45bc8a41dba1b1d7636f033ae656b189993687","sources":[{"modifiedAt":1793916512749,"name":"CNA: GitHub_M","retrievedAt":1793920185686,"url":"https://www.cve.org/CVERecord?id=CVE-2026-88986"}],"ssvc":null,"status":"published","title":"Kubeflow Pipelines: Reflected XSS in the frontend pod information and events error responses","updatedAt":1793920185686}
