• CVE-2022-25207: 0.72% estimated exploitation activity in the next 30 days; percentile 53.88 (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 Chef Sinatra Plugin 1.20 and earlier does not perform a permission check in a method implementing form validation. This allows attackers with Overall/Read permission to have Jenkins send an HTTP request to an attacker-controlled URL and have it parse the response as XML. As the plugin does not configure its XML parser to prevent XML external entity (XXE) attacks, attackers can have Jenkins parse a crafted XML response that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery. Additionally, this form validation method does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

# Patch Next advisory brief: CVE-2022-25207

Advisory: CSRF vulnerability in Jenkins Chef Sinatra Plugin allow XXE
IDs: CVE-2022-25207, GHSA-x92v-xv3x-9v29
Record: https://patchnext.com/advisories/cve-2022-25207 (revision 1, source checked 26 Oct 2026, 16:15 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:sinatra-chef-builder: affected <= 1.20

## Suggested inspection (read-only)
- Maven org.jenkins-ci.plugins:sinatra-chef-builder: 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:sinatra-chef-builder.
- 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-x92v-xv3x-9v29 (GitHub-reviewed advisory GHSA-x92v-xv3x-9v29 lists affected ranges: Maven org.jenkins-ci.plugins:sinatra-chef-builder >=0 <=1.20)
