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

Build Pipeline Plugin does not properly escape variables in views, resulting in a stored cross-site scripting vulnerability exploitable by users with permission to configure build pipelines.

This vulnerability is only exploitable on Jenkins releases older than 2.146 or 2.138.2 due to the security hardening implemented in those releases.

As of publication of this advisory, there is no fix.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:build-pipeline-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 org.jenkins-ci.plugins:build-pipeline-plugin for CVE-2019-10373. 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.
