Description

A cross-site scripting vulnerability exists in Jenkins Warnings Next Generation Plugin 1.0.1 and earlier in src/main/java/io/jenkins/plugins/analysis/core/model/DetailsTableModel.java, src/main/java/io/jenkins/plugins/analysis/core/model/SourceDetail.java, src/main/java/io/jenkins/plugins/analysis/core/model/SourcePrinter.java, src/main/java/io/jenkins/plugins/analysis/core/util/Sanitizer.java, src/main/java/io/jenkins/plugins/analysis/warnings/DuplicateCodeScanner.java that allows attackers with the ability to control warnings parser input to have Jenkins render arbitrary HTML.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update io.jenkins.plugins:warnings-ng to 2.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2019-1003023 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.
