GHSA-f8h4-46xv-h7jj
HIGHGHSA-f8h4-46xv-h7jj is a high-severity (CVSS 8) Cross-site Scripting (XSS) vulnerability in org.jenkins-ci.plugins:htmlpublisher. O3 Security confirms whether GHSA-f8h4-46xv-h7jj is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Jenkins HTML Publisher Plugin has a XSS vulnerability in the legacy wrapper file
Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for GHSA-f8h4-46xv-h7jj.
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-f8h4-46xv-h7jj 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 356,453 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

Description
Jenkins HTML Publisher Plugin versoins 427 and earlier do not escape the job name and URL in the legacy wrapper file.
This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.
HTML Publisher Plugin 427.1 escapes job name and URL when generating the legacy wrapper file.

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:htmlpublisher. 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 org.jenkins-ci.plugins:htmlpublisher to 427.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f8h4-46xv-h7jj 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-f8h4-46xv-h7jj 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-f8h4-46xv-h7jj. 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-f8h4-46xv-h7jj in your dependencies?
O3 detects GHSA-f8h4-46xv-h7jj across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
