The CVE-2025-XXXX vulnerability in Jenkins stems from an authorization flaw within the user interface’s sidepanel component. A specific view, designed to be accessible to users who lack the Overall/Read system permission, incorrectly renders a sidepanel. This sidepanel contains an executors widget that dynamically fetches and displays the names of all connected build agents. The core issue is that the application logic fails to perform a necessary permission check before populating this widget with sensitive data. Consequently, an attacker with minimal user-level access can navigate to this intentionally permissive page. By viewing the page source or intercepting the network traffic generated by the widget, the attacker can enumerate the names of every agent configured within the Jenkins instance, information that should be restricted.
