Source description

As published by the source; long descriptions are shortened.

SourceMonitor Plugin 0.2 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks. This allows attackers able to control XML input files for the 'Publish SourceMonitor results' post-build step to have agent processes parse a crafted file that uses external entities for extraction of secrets from the Jenkins agent or server-side request forgery. Because Jenkins agent processes usually execute build tools whose input (source code, build scripts, etc.) is controlled externally, this vulnerability only has a real impact in very narrow circumstances: when attackers can control XML files, but are unable to change build steps, Jenkinsfiles, test code that gets executed on the agents, or similar.

# Patch Next advisory brief: CVE-2022-45396

Advisory: XXE vulnerability on agents in Jenkins SourceMonitor Plugin
IDs: CVE-2022-45396, GHSA-h4wx-78p9-fwxw
Record: https://patchnext.com/advisories/cve-2022-45396 (revision 1, source checked 26 Oct 2026, 16:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.4)
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 com.thalesgroup.hudson.plugins:sourcemonitor: affected <= 0.2

## Suggested inspection (read-only)
- Maven com.thalesgroup.hudson.plugins:sourcemonitor: 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 com.thalesgroup.hudson.plugins:sourcemonitor.
- 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-h4wx-78p9-fwxw (GitHub-reviewed advisory GHSA-h4wx-78p9-fwxw lists affected ranges: Maven com.thalesgroup.hudson.plugins:sourcemonitor >=0 <=0.2)

Commands are suggestions: review each one before running it.
