Summary
Memory usage graphs accessible to anyone with Overall/Read
Details

Jenkins includes a feature that shows a JVM memory usage chart for the Jenkins controller.

Access to the chart in Jenkins 2.218 and earlier, LTS 2.204.1 and earlier requires no permissions beyond the general Overall/Read, allowing users who are not administrators to view JVM memory usage data.

Jenkins 2.219, LTS 2.204.2 now requires Overall/Administer permissions to view the JVM memory usage chart.

Severity
4.3 (Medium)
