Advisory Summary

CVE-2026-13489 is a LOW (CVSS 3.1) security vulnerability vulnerability (CWE-662: Improper Synchronization) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product utilizes multiple threads, processes, components, or systems to allow temporary access to a shared resource that can only be exclusive to one process at a time, but it does not properly synchronize these actions, which might cause simultaneous accesses of this resource by multiple threads or processes.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-13489

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-2026-13489, 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-662: Improper Synchronization, where the product utilizes multiple threads, processes, components, or systems to allow temporary access to a shared resource that can only be exclusive to one process at a time, but it does not properly synchronize these actions, which might cause simultaneous accesses of this resource by multiple threads or processes. 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 weakness has been identified in 78 xiaozhi-esp32 up to 2.2.6. Affected by this issue is the function ParseMessage of the file main/mcp_server.cc of the component MCP Response Handler. This manipulation causes improper synchronization. Remote exploitation of the attack is possible. The attack's complexity is rated as high. The exploitation is known to be difficult. The exploit has been made available to the public and could be used for attacks. The pull request to fix this issue awaits acceptance.
