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
Jenkins GitLab Plugin 1.5.31 and earlier does not perform a permission check in an HTTP endpoint, allowing attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins. An enumeration of credentials IDs in GitLab Plugin 1.5.32 requires the appropriate permissions.

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 1.5.32 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5phj-qv74-pv4w 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.
