Warning |
What does Kentico 12.x end of life mean?
When Kentico 12.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 Kentico 12.x past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to a supported version or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
Frequently Asked Questions

What should I upgrade to from Kentico 12.x?
What are the security risks of running Kentico 12.x past EOL?
When Kentico 12.x reaches end of life, the maintainers stop issuing security patches. Any CVEs disclosed after the EOL date accumulate with no vendor fix.

Organizations running EOL Kentico should migrate immediately or implement compensating controls.
