Publication date: 2026-10-07

Last updated on: 2026-10-07

Assigner: Apache Software Foundation

Description
Apache YuniKorn 1.9.0 and earlier allows bypassing the check for the user annotation by setting a secondary label on the pod. If the pod has the label 'app=yunikorn' the checks limiting the user annotation content are not run. The label is used to identify the YuniKorn application itself in the deployments. The bypass allows any user to specify an arbitrary user info annotation. The arbitrary user information could allow access to a queue that the user normally would not have access to. Quota usage for the queue might be impacted if the application runs in the incorrect queue. User based quota enforcement is also based on the user annotation. User quota tracking could be side stepped even if the application runs in the correct queue. Users are recommended to upgrade to version 1.10.0, which fixes this issue.

Executive Summary

This vulnerability in Apache YuniKorn 1.9.0 and earlier allows bypassing user annotation checks by setting a secondary label on a pod with the label 'app=yunikorn'. This bypass enables users to specify arbitrary user info annotations, potentially granting access to restricted queues or bypassing user-based quota enforcement.

Detection Guidance

To detect this vulnerability, check for pods with the label 'app=yunikorn' and verify if they have arbitrary user info annotations set. Inspect pod specifications for unexpected annotations or labels that could bypass security checks.

Impact Analysis

The vulnerability could allow unauthorized access to queues you normally wouldn't have permission to use. It may also impact quota usage tracking, as user-based quotas could be bypassed even if the application runs in the correct queue.

Compliance Impact

This vulnerability could impact compliance with standards like GDPR and HIPAA by allowing unauthorized access to queues and bypassing user-based quota enforcement. Arbitrary user info annotations might lead to improper access controls, potentially violating data protection requirements for confidentiality and integrity.

Mitigation Strategies

Upgrade Apache YuniKorn to version 1.10.0 or later to address the bypass vulnerability. Review pods with the 'app=yunikorn' label to ensure no unauthorized user annotations are present.
