EPSS

• CVE-2022-43432: 0.66% estimated exploitation activity in the next 30 days; percentile 51.82 (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 sets the Content-Security-Policy header to static files served by Jenkins (specifically DirectoryBrowserSupport), such as workspaces, /userContent, or archived artifacts, unless a Resource Root URL is specified. XFramium Builder Plugin 1.0.22 and earlier globally disables the Content-Security-Policy header for static files served by Jenkins as soon as it is loaded. This allows cross-site scripting (XSS) attacks by users with the ability to control files in workspaces, archived artifacts, etc. Jenkins instances with Resource Root URL configured are unaffected.

# Patch Next advisory brief: CVE-2022-43432

Advisory: Content-Security-Policy protection for user content disabled by Jenkins XFramium Builder Plugin
IDs: CVE-2022-43432, GHSA-px4x-hjm5-w8x3
Record: https://patchnext.com/advisories/cve-2022-43432 (revision 1, source checked 26 Oct 2026, 16:07 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jenkins-ci.plugins:xframium: affected <= 1.0.22

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

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.jenkins-ci.plugins:xframium.
- 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-px4x-hjm5-w8x3 (GitHub-reviewed advisory GHSA-px4x-hjm5-w8x3 lists affected ranges: Maven org.jenkins-ci.plugins:xframium >=0 <=1.0.22)
