CVE-2026-88986 · Severity: medium · CVSS 6.1 · Published 2026-11-05

Kubeflow Pipelines is a machine learning workflow management system used to build and deploy scalable ML pipelines. The frontend endpoints for viewing pod information and logs fail to sanitize user-supplied query parameters, allowing an attacker to inject and execute arbitrary JavaScript in a user's browser. A malicious link could steal session cookies or perform actions on behalf of an authenticated user.

Technical details

Reflected XSS vulnerability in frontend routes /pipeline/k8s/pod and /pipeline/k8s/pod/events due to unsanitized podname and podnamespace query parameters being included in HTML-capable error responses. An unauthenticated attacker can craft a malicious link containing script payloads that executes in the frontend origin when clicked by a user with deployment authentication and route access. Cookie disclosure risk depends on cookie attributes; no server-side code execution or availability impact established.

Affected products
