Real-World Exposure
org.jenkins-ci.plugins:gatlingReal-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
Gatling Plugin 1.2.7 and earlier serves Gatling reports in a manner that bypasses the Content-Security-Policy protection introduced in Jenkins 1.641 and 1.625.3. This results in a cross-site scripting (XSS) vulnerability exploitable by users able to change report content.
Gatling Plugin 1.3.0 no longer allows viewing Gatling reports directly in Jenkins. Instead users need to download an archive containing the report.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:gatling, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.jenkins-ci.plugins:gatling to 1.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hv53-qjg6-5pm9 is resolved across your whole dependency graph.
Workarounds
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
