Real-World Exposure
org.jenkins-ci.plugins:sinatra-chef-builderReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
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.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:sinatra-chef-builder, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of org.jenkins-ci.plugins:sinatra-chef-builder for GHSA-x92v-xv3x-9v29. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.
