• CVE-2024-39458: 0.44% estimated exploitation activity in the next 30 days; percentile 38.24 (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.

Structs Plugin provides utility functionality used, e.g., in Pipeline to instantiate and configure build steps, typically before their execution. When Structs Plugin 337.v1b04ea4df7c8 and earlier fails to configure a build step, it logs a warning message containing diagnostic information that may contain secrets passed as step parameters. This can result in accidental exposure of secrets through the default system log. Structs Plugin 338.v848422169819 inspects the types of actual parameters before logging these warning messages, and limits detailed diagnostic information to FINE level log messages if secrets are involved. These log messages are not displayed in the default Jenkins system log.

# Patch Next advisory brief: CVE-2024-39458

Advisory: Exposure of secrets through system log in Jenkins Structs Plugin
IDs: CVE-2024-39458, GHSA-xfx3-cr74-x3cv
Record: https://patchnext.com/advisories/cve-2024-39458 (revision 1, source checked 26 Oct 2026, 16:31 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 2.3)
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:structs 338.v848422169819. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jenkins-ci.plugins:structs: affected < 338.v848422169819; fixed in 338.v848422169819

## Suggested inspection (read-only)
- Maven org.jenkins-ci.plugins:structs: 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:structs.
- 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-xfx3-cr74-x3cv (GitHub-reviewed advisory GHSA-xfx3-cr74-x3cv lists affected ranges: Maven org.jenkins-ci.plugins:structs >=0 <338.v848422169819)
