# CVE-2026-88985: Kubeflow Pipelines: SQL injection through unvalidated pagination tokens in Kubeflow Pipelines API server

Status: published. Published: 2026-11-05. Updated: 2026-11-05.

Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.17.0, the API server trusts structural SQL identifier fields decoded from the base64-encoded JSON page_token parameter before constructing list queries. An attacker who can invoke an affected pipeline or run list API can inject through KeyFieldName or SortByFieldName, including v1beta1 and v2beta1 run-listing metric paths, and read data available to the API server database account across namespaces. Database modification is not established. This issue is fixed in version 2.17.0.
