Advisory Summary

CVE-2026-73729 is a MODERATE (CVSS 6.5) security vulnerability vulnerability (CWE-269: Improper Privilege Management) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-73729

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-2026-73729, 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-269: Improper Privilege Management, where the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. 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

A vulnerability in the underlying operating system of HPE Networking Fabric Composer could allow an authenticated low privilege operator user with local access to upstream AFC dependencies to view sensitive information. Successful exploitation could allow an attacker to access data beyond what is authorized by the user's existing privilege level, potentially leading to further unauthorized access.
