GHSA-5m4q-x28v-q6wp is a medium-severity (CVSS 4.3) CWE-862 vulnerability in io.jenkins.blueocean:blueocean-parent. O3 Security confirms whether GHSA-5m4q-x28v-q6wp is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Missing permission check in Jenkins Blue Ocean Plugin
Real-World Exposure
io.jenkins.blueocean:blueocean-parentReal-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 Blue Ocean Plugin 1.25.3 and earlier does not perform a permission check in several HTTP endpoints, allowing attackers with Overall/Read permission to connect to an attacker-specified HTTP server. Blue Ocean Plugin 1.25.4 requires POST requests and the appropriate permissions for the affected HTTP endpoints.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jenkins.blueocean:blueocean-parent. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update io.jenkins.blueocean:blueocean-parent to 1.25.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5m4q-x28v-q6wp is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-5m4q-x28v-q6wp is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-5m4q-x28v-q6wp. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-5m4q-x28v-q6wp in your dependencies?
O3 detects GHSA-5m4q-x28v-q6wp across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
