What is CVE-2023-32977?

CVE-2023-32977 is a high-severity cross-site scripting (XSS) vulnerability in org.jenkins-ci.plugins.workflow:workflow-job (maven), affecting versions < 1295.v395eb. It is fixed in 1295.v395eb. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.

How severe is CVE-2023-32977?

CVE-2023-32977 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

Which versions of org.jenkins-ci.plugins.workflow:workflow-job are affected by CVE-2023-32977?

org.jenkins-ci.plugins.workflow:workflow-job (maven) versions < 1295.v395eb is affected.

Is there a fix for CVE-2023-32977?

Yes. CVE-2023-32977 is fixed in 1295.v395eb. Upgrade to this version or later.

Is CVE-2023-32977 exploitable, and should I be worried?

Whether CVE-2023-32977 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2023-32977 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

Summary

Jenkins Pipeline: Job Plugin vulnerable to stored Cross-site Scripting

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.

Impact

Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.

CVE-2023-32977 has a CVSS score of 7.5 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1295.v395eb); upgrading removes the vulnerable code path.

Affected versions

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
