CVE-2019-1003013
MEDIUMCross-site Scripting in Jenkins Blue Ocean Plugin
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.

Description
An cross-site scripting vulnerability exists in Jenkins Blue Ocean Plugins 1.10.1 and earlier in blueocean-commons/src/main/java/io/jenkins/blueocean/commons/stapler/Export.java, blueocean-commons/src/main/java/io/jenkins/blueocean/commons/stapler/export/ExportConfig.java, blueocean-commons/src/main/java/io/jenkins/blueocean/commons/stapler/export/JSONDataWriter.java, blueocean-rest-impl/src/main/java/io/jenkins/blueocean/service/embedded/UserStatePreloader.java, blueocean-web/src/main/resources/io/jenkins/blueocean/PageStatePreloadDecorator/header.jelly that allows attackers with permission to edit a user's description in Jenkins to have Blue Ocean render arbitrary HTML when using it as that user.

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. 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 to 1.10.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2019-1003013 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 CVE-2019-1003013 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 CVE-2019-1003013. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2019-1003013 in your dependencies?
O3 detects CVE-2019-1003013 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
