EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-w2j3-pq63-339w plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 379,145 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
org.jenkins-ci.plugins:support-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
Support Core Plugin defines the permission Support/DownloadBundle that allows users without Overall/Administer permission to create and download support bundles containing a limited set of diagnostic information.
Support Core Plugin 1206.v14049fa_b_d860 and earlier does not correctly perform permission checks in several HTTP endpoints.
This allows attackers with Support/DownloadBundle permission to download a previously created support bundle containing information limited to users with Overall/Administer permission.
Support Core Plugin 1206.1208.v9b_7a_1d48db_0f deprecates the Support/DownloadBundle permission. The Overall/Administer permission is now required to download support bundles.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:support-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.jenkins-ci.plugins:support-core to 1206.1208.v9b_7a_1d48db_0f or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-w2j3-pq63-339w 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-w2j3-pq63-339w can be triaged on real exposure rather than presence alone.
Tailored to GHSA-w2j3-pq63-339w. 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-w2j3-pq63-339w in your dependencies?
O3 Security finds GHSA-w2j3-pq63-339w across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
