Advisory Summary

CVE-2026-12593 is a HIGH security vulnerability vulnerability (CWE-862: Missing Authorization) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product does not perform an authorization check when an actor attempts to access a resource or perform an action.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-12593

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-2026-12593, 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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. 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

The implementation of an internal and undocumented Dashboard API endpoint (POST /api/users/~/{user}/tokens) forgot to ensure an HTTP request for creating an API Token for another user had sufficient permission to do so. Precondition for successful exploitation was a preexisting internal user (with more privileges than the attacker), the attacker knowing its login name and the attacker being able to authenticate to the Dashboard via OAuth/OIDC. The attacker would then have had to forge a token creation API request on behalf of the other user and could have authenticated and finalized the token creation with their own OAuth/OIDC credentials. In the worst case, this would mean an attacker could have become Dashboard Administrator and been able to perform all administrative actions if the preexisting internal user had administrative privileges. In combination with a separate weakness, this could have further led to code execution on the host system running the Dashboard with the privileges of the OS-User running the Dashboard server.
