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 Pipeline: Job Plugin 1292.v27d8cc3e2602 and earlier does not escape the display name of the build that caused an earlier build to be aborted, when "Do not allow concurrent builds" is set.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to set build display names immediately.

The Jenkins security team is not aware of any plugins that allow the exploitation of this vulnerability, as the build name must be set before the build starts. Pipeline: Job Plugin 1295.v395eb_7400005 escapes the display name of the build that caused an earlier build to be aborted.

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.workflow:workflow-job, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins.workflow:workflow-job to 1295.v395eb or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-32977 is resolved across your whole dependency graph.

  3. 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.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Red HatImportant

OpenShift 3.11 is in ELS. Jenkins and its related technologies will not be supported under ELS. Hence, OpenShift 3.11 is marked as affected/won'tfix.
