How to Fix CVE-2026-97146

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-97146, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-290: Authentication Bypass by Spoofing, where this attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
