Do this: Apply the patch, or workarounds offered by Atlassian, as soon as possible.
Why: Multiple versions of Jira Data Center and Jira Service Management Data Center are affected by CVE-2020-36239, a critical bug that could enable unauthenticated remote code execution within the Data Center products. The patch fixes the issue but now requires a shared secret in order to access the Ehcache service. The workaround is to restrict access to the Ehcache remote invocation (RMI) ports (40001 and 40011).
