CVE-2026-97146Network attack vectorHinoki check available

Queue access bypass via forged system pod label

Published Oct 7, 2026 · Updated Oct 7, 2026

Improper authorization in Apache YuniKorn 1.9.0 and earlier allows remote authenticated users to bypass pod user-annotation checks. The admission controller treats the app=yunikorn pod label as a system-pod exemption without verifying its namespace, so a forged label skips user-info validation. A user able to submit pods can supply arbitrary identity metadata, undermining queue access controls and user quota tracking.
