CVE-2022-27196Network attack vector

Stored XSS via unescaped job names

Published Mar 15, 2022 · Updated Aug 3, 2024

Cross-site scripting in Jenkins Favorite Plugin 2.4.0 and earlier allows remote authenticated users to execute script via crafted job names. The favorite-column renderer inserts job names without escaping, so a permitted user can store script content that runs when the column is viewed. Item/Configure or Item/Create permission is required, and the consequence is browser-session compromise rather than direct Jenkins server execution.
