</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.activemqHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-49270, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.activemqAnalyze 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-1230: Exposure of Sensitive Information Through Metadata, where the product prevents direct access to a resource containing sensitive information, but it does not sufficiently limit access to metadata that is derived from the original, sensitive information. In Apache activemq, software state validation or input boundaries are circumvented during processing.
