CVE-2022-41239Network attack vector

Stored script execution via unescaped GitHub username

Published Sep 21, 2022 · Updated May 28, 2025

Stored XSS in Jenkins DotCi Plugin 2.40.00 and earlier allows remote attackers to run script in a viewer's browser via commit notifications. The plugin stores the GitHub username from a commit notification and renders it in a build cause without escaping the value for HTML output. Exploitation requires a crafted notification to reach /githook/ and a Jenkins user to view the cause, and it applies only through Jenkins 2.314 or LTS 2.303.1.
