Warning |
What does Clickhouse 26.2 end of life mean?
When Clickhouse 26.2 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: Most vulnerability scanners check for known CVEs but do not flag the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Running Clickhouse 26.2 past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.
Migrate to Clickhouse 26.4 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
