Microsoft has released security updates: Exchange Server 2013,  Exchange Server 2016,  Exchange Server 2019

Vulnerabilities addressed in the April 2021 security updates were responsibly reported to Microsoft by a security partner. Although we are not aware of any active exploits in the wild, our recommendation is to install these updates immediately to protect your environment.

These vulnerabilities affect Microsoft Exchange Server. Exchange Online customers are already protected and do not need to take any action.

For additional information, please see the Microsoft Security Response Center (MSRC) blog. More details about specific CVEs can be found in Security Update Guide (filter on Exchange Server under Product Family).
