EPSS

• CVE-2023-40340: 0.63% estimated exploitation activity in the next 30 days; percentile 50.40 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2023-40340

Advisory: Jenkins NodeJS Plugin improper credential masking vulnerability
IDs: CVE-2023-40340, GHSA-36fg-whr2-g999
Record: https://patchnext.com/advisories/cve-2023-40340 (revision 1, source checked 26 Oct 2026, 16:24 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.jenkins-ci.plugins:nodejs 1.6.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jenkins-ci.plugins:nodejs: affected < 1.6.1; fixed in 1.6.1

## Suggested inspection (read-only)
- Maven org.jenkins-ci.plugins:nodejs: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.jenkins-ci.plugins:nodejs.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-36fg-whr2-g999 (GitHub-reviewed advisory GHSA-36fg-whr2-g999 lists affected ranges: Maven org.jenkins-ci.plugins:nodejs >=0 <1.6.1)
