How severe is CVE-2023-25762?

CVE-2023-25762 has a CVSS score of 5.4/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2023-25762?

CVE-2023-25762 affects the following packages: org.jenkins-ci.plugins:pipeline-build-step (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-25762?

Update org.jenkins-ci.plugins:pipeline-build-step to 2.18.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-25762 is resolved across your whole dependency graph.

How do I detect CVE-2023-25762 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:pipeline-build-step, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2023-25762 if there is no patch (or I can't update yet)?

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.

Is CVE-2023-25762 actively exploited in the wild?

No public exploit code has been indexed for CVE-2023-25762 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2023-25762?

CVE-2023-25762 has an EPSS (Exploit Prediction Scoring System) score of 82.1%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

What type of vulnerability is CVE-2023-25762?

CVE-2023-25762 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2023-25762 published, and has it been updated?

CVE-2023-25762 was published on February 15, 2023 and was last updated on October 24, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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 HatModerate

OpenShift 3.11 is already in the ELS support model phase. The Jenkins components are out of scope of the ELS support, therefore, the OpenShift 3.11 Jenkins component is marked as out of support scope in this CVE.
