What does Dynamics 365 Business Central on-premises 2022 release wave 2, version 21.x end of life mean?
When Dynamics 365 Business Central on-premises 2022 release wave 2, version 21.x reaches end of life, the maintainers stop issuing security patches for this version. CVEs discovered after the EOL date are publicly disclosed on the National Vulnerability Database with no patch available. Exploit code frequently appears on GitHub within days of disclosure.
The CVE blind spot: A CVE-based scan does not show the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Some scanners flag unsupported versions of common products, but coverage varies, and none of them give you the date in advance. Running Dynamics 365 Business Central on-premises 2022 release wave 2, version 21.x past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to Dynamics 365 Business Central on-premises 2026 release wave 2, version 29.x or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
