Real-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 Mashup Portlets Plugin 1.1.2 and earlier provides the "Generic JS Portlet" feature that lets a user populate a portlet using a custom JavaScript expression.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by authenticated attackers with Overall/Read permission.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for javagh.jenkins:mashup-portlets-plugin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of javagh.jenkins:mashup-portlets-plugin for GHSA-h9h3-jx58-6hqq. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    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.
