Recommendation
For Confluence Data Center and Server instances publicly accessible, temporarily restrict external access until the upgrade.
If that’s not possible, apply for interim protection by blocking /setup/* endpoint access at the network level or by adjusting Confluence configuration files.
Then restart the Confluence, as this step restricts access to unnecessary setup pages in Confluence.
