SSL/TLS certificate validation disabled by default in Jenkins Checkmarx Plugin

CVE-2023-35142GHSA-rr3p-5fcf-v5m3

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (com.checkmarx.jenkins:checkmarx 2023.2.6), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2023-35142

Advisory: SSL/TLS certificate validation disabled by default in Jenkins Checkmarx Plugin
IDs: CVE-2023-35142, GHSA-rr3p-5fcf-v5m3
Record: https://patchnext.com/advisories/cve-2023-35142 (revision 1, source checked 26 Oct 2026, 16:26 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: com.checkmarx.jenkins:checkmarx 2023.2.6. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.checkmarx.jenkins:checkmarx: affected <= 2022.4.3; fixed in 2023.2.6

## Suggested inspection (read-only)
- Maven com.checkmarx.jenkins:checkmarx: 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 com.checkmarx.jenkins:checkmarx.
- 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-rr3p-5fcf-v5m3 (GitHub-reviewed advisory GHSA-rr3p-5fcf-v5m3 lists affected ranges: Maven com.checkmarx.jenkins:checkmarx >=0 <=2022.4.3)

Commands are suggestions: review each one before running it.
