Details
As written in the advisory (Markdown source, shown as plain text).
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.
