Real-World Exposure
org.jenkins-ci.plugins:gitlab-pluginReal-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
The Jenkins GitLab Plugin 1.9.6 and earlier does not correctly perform a permission check in an HTTP endpoint.
This allows attackers with global Item/Configure permission (while lacking Item/Configure permission on any particular job) to enumerate credential IDs of GitLab API token credentials and Secret text credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability.
An enumeration of credential IDs in GitLab Plugin 1.9.7 requires Overall/Administer permission.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:gitlab-plugin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.jenkins-ci.plugins:gitlab-plugin to 1.9.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xhgq-h98j-859v is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
