# Patch Next advisory brief: CVE-2023-40338

Advisory: Jenkins Folders Plugin information disclosure vulnerability
IDs: CVE-2023-40338, GHSA-36hq-v2fc-rpqp
Record: https://patchnext.com/advisories/cve-2023-40338 (revision 1, source checked 26 Oct 2026, 16:16 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:cloudbees-folder 6.848.ve3b. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jenkins-ci.plugins:cloudbees-folder: affected < 6.848.ve3b; fixed in 6.848.ve3b

## Suggested inspection (read-only)
- Maven org.jenkins-ci.plugins:cloudbees-folder: 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:cloudbees-folder.
- 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-36hq-v2fc-rpqp (GitHub-reviewed advisory GHSA-36hq-v2fc-rpqp lists affected ranges: Maven org.jenkins-ci.plugins:cloudbees-folder >=0 <6.848.ve3b)
