Description
CVE-2026-88986 is a cross-site scripting (XSS) vulnerability in Kubeflow Pipelines prior to version 2.15.0. It affects the frontend routes /pipeline/k8s/pod and /pipeline/k8s/pod/events, where untrusted query parameters are included in HTML-capable error responses. An unauthenticated attacker can craft a malicious link that executes JavaScript in the frontend origin when visited by an authenticated user with route access. The vulnerability allows limited impact such as cookie disclosure depending on cookie attributes, but does not establish server-side code execution or availability impact. The issue is fixed in version 2.15.0.
