How to Fix CVE-2023-40340

To remediate this vulnerability, upgrade all affected Nodejs 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.jenkins-ci.plugins:nodejs fixed: 1.6.1 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>nodejs</artifactId>
    <version>1.6.1</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.jenkins-ci.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-40340, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.jenkins-ci.plugins

Analyze the terminal output to locate any version of Nodejs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.6.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.jenkins-ci.plugins 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 Nodejs, 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

Jenkins NodeJS Plugin integrates with Config File Provider Plugin to specify custom NPM settings, including credentials for authentication, in a Npm config file. NodeJS Plugin 1.6.0 and earlier does not properly mask (i.e., replace with asterisks) credentials specified in the Npm config file in Pipeline build logs. NodeJS Plugin 1.6.1 masks credentials specified in the Npm config file in Pipeline build logs.
