How to Fix CVE-2026-44930

To remediate this vulnerability, upgrade all affected Cxf services xkms x509 repo ldap 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.cxf.services.xkms:cxf-services-xkms-x509-repo-ldap fixed: 4.2.1
<dependency>
    <groupId>org.apache.cxf.services.xkms</groupId>
    <artifactId>cxf-services-xkms-x509-repo-ldap</artifactId>
    <version>4.2.1</version>
</dependency>
org.apache.cxf.services.xkms:cxf-services-xkms-x509-repo-ldap fixed: 4.1.6
<dependency>
    <groupId>org.apache.cxf.services.xkms</groupId>
    <artifactId>cxf-services-xkms-x509-repo-ldap</artifactId>
    <version>4.1.6</version>
</dependency>
org.apache.cxf.services.xkms:cxf-services-xkms-x509-repo-ldap fixed: 3.6.11
<dependency>

    <artifactId>cxf-services-xkms-x509-repo-ldap</artifactId>
    <version>3.6.11</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.cxf.services.xkms

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-44930, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.cxf.services.xkms

Analyze the terminal output to locate any version of Cxf services xkms x509 repo ldap 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.services.xkms 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-90: Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection'), where the product constructs all or part of an ldap query using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended ldap query when it is sent to a downstream component. In Cxf services xkms x509 repo ldap, 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
