CVE-2026-44417: Apache CXF Remote Code Execution Vulnerability
HIGHCVE-2026-44417 is a HIGH (CVSS 7.5) remote code execution vulnerability (CWE-20: Improper Input Validation) affecting Apache CXF libraries in the Maven ecosystem. The issue involves untrusted jms configuration can lead to rce. Remediation is available by upgrading affected packages to version 4.2.1, 4.1.6, 3.6.11.

How to Fix CVE-2026-44417
To remediate this vulnerability, upgrade all affected Apache CXF dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-jms</artifactId>
<version>4.2.1</version>
</dependency><dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-jms</artifactId>
<version>4.1.6</version>
</dependency><dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-jms</artifactId>
<version>3.6.11</version>
</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.cxfHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-44417, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.cxfAnalyze the terminal output to locate any version of Apache CXF in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.2.1), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.cxf 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Apache CXF, 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.
