How to Fix GHSA-94g7-hpv8-h9qm

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

com.splunk.logging:splunk-library-javalogging fixed: 1.11.1 
<dependency>
    <groupId>com.splunk.logging</groupId>
    <artifactId>splunk-library-javalogging</artifactId>
    <version>1.11.1</version>
</dependency>
com.splunk.logging:splunk-library-javalogging fixed: 1.6.2-0-0 
<dependency>
    <groupId>com.splunk.logging</groupId>
    <artifactId>splunk-library-javalogging</artifactId>
    <version>1.6.2-0-0</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=com.splunk.logging

How to Check if You Are Affected

To determine whether your Java application is affected by GHSA-94g7-hpv8-h9qm, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.splunk.logging

Analyze the terminal output to locate any version of Splunk library javalogging in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.11.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.splunk.logging 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 General Security Weakness. In Splunk library javalogging, 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

### Impact Logging untrusted or user controlled data with a vulnerable version of Log4J may result in Remote Code Execution (RCE) against your application. This includes untrusted data included in logged errors such as exception traces, authentication failures, and other unexpected vectors of user controlled input. More Details: https://github.com/advisories/GHSA-jfh8-c2jp-5v3q ### Patches Version 1.11.1 of the Splunk Logging for Java library. There is also a backport to version 1.6.2 released as a patch: 1.6.2-0-0. ### Workarounds If upgrading is not possible, then ensure the -Dlog4j2.formatMsgNoLookups=true system property is set on both client- and server-side components. ### References https://github.com/advisories/GHSA-jfh8-c2jp-5v3q ### For more information If you have any questions or comments about this advisory: * Open an issue in https://github.com/splunk/splunk-library-javalogging/issues * Email us at [devinfo@splunk.com](mailto:devinfo@splunk.com)
