CVE-2026-84654Network attack vectorHinoki check available

Global configuration changes via static-field binding

Published Sep 2, 2026 · Updated Sep 2, 2026

Improper form binding in Jenkins 2.579 and earlier and LTS 2.568.2 and earlier allows remote authenticated users to change global settings. Stapler binds submitted configuration-form values into public static fields of configuration objects instead of excluding class-wide state. Submitting an accessible configuration form is required; any bound public static field can then be changed for the entire instance.
