• CVE-2026-57287: 0.19% estimated exploitation activity in the next 30 days; percentile 9.31 (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 Job Configuration History Plugin 1356.ve360da6c523a and earlier does not redact the encrypted values of secrets when displaying historical job and agent configurations through its "View as XML" / "(RAW)" feature and its configuration diff views. This allows attackers with Item/Extended Read permission (but not Item/Configure permission) to view the encrypted values of secrets, such as build trigger tokens, that Jenkins would otherwise redact from the configuration shown to them. Job Configuration History Plugin 1367.vc8fab15101dc redacts the encrypted values of secrets when displaying historical job and agent configurations through its "View as XML" / "(RAW)" feature and its configuration diff views to users lacking Item/Configure permission.

# Patch Next advisory brief: CVE-2026-57287

Advisory: Jenkins Job Configuration History Plugin doesn't redact encrypted values of secrets in job and agent configurations
IDs: CVE-2026-57287, GHSA-8qr4-27mh-hqfr
Record: https://patchnext.com/advisories/cve-2026-57287 (revision 1, source checked 26 Oct 2026, 16:55 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:jobConfigHistory 1367. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jenkins-ci.plugins:jobConfigHistory: affected < 1367; fixed in 1367

## Suggested inspection (read-only)
- Maven org.jenkins-ci.plugins:jobConfigHistory: 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:jobConfigHistory.
- 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-8qr4-27mh-hqfr (GitHub-reviewed advisory GHSA-8qr4-27mh-hqfr lists affected ranges: Maven org.jenkins-ci.plugins:jobConfigHistory >=0 <1367)
