How to Fix CVE-2026-46605

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

org.apache.activemq:apache-activemq fixed: 5.19.7 
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>apache-activemq</artifactId>
    <version>5.19.7</version>
</dependency>
org.apache.activemq:apache-activemq fixed: 6.2.6 
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>apache-activemq</artifactId>
    <version>6.2.6</version>
</dependency>
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 -Dincludes=org.apache.activemq

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-46605, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.activemq

Analyze the terminal output to locate any version of Apache activemq in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.19.7), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.activemq 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-285: Improper Authorization, where the product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. In Apache activemq, software state validation or input boundaries are circumvented during processing.
