CVE-2022-34783Network attack vector

Stored XSS via unescaped plot descriptions

Published Jun 30, 2022 · Updated Aug 3, 2024

Stored XSS in Jenkins Plot Plugin 2.1.10 and earlier allows remote authenticated users to execute script in a viewer's browser. The PlotReport/index.jelly view renders the saved description with j:out; the patch replaces it with a span that applies Jenkins Jelly escaping. Item/Configure permission is required to store the payload, and a separate user must view the affected report for the script to run in that user's browser.
