What does Kirby 5 end of life mean?
When Kirby 5 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 Kirby 5 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to Kirby 5 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
