Real-World Exposure
org.jenkins-ci.main:jenkins-core☕org.jenkins-ci.main:jenkins-coreReal-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 2.527 and earlier, LTS 2.516.2 and earlier does not perform a permission check for the authenticated user profile dropdown menu. This allows attackers without Overall/Read permission to obtain limited information about the Jenkins configuration by listing available options in this menu (e.g., whether Credentials Plugin is installed).
Jenkins 2.528, LTS 2.516.3 requires Overall/Read permission to list various items in authenticated user profile dropdown menus.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.main:jenkins-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.jenkins-ci.main:jenkins-core to 2.516.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-223m-4rfp-646h 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.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.Source: Red Hat security advisory for GHSA-223m-4rfp-646h (CC BY 4.0)
