What does MariaDB 12.3 end of life mean?

When MariaDB 12.3 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 MariaDB 12.3 past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.

Migrate to MariaDB 12.3 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.

What are the security risks of running MariaDB 12.3 past EOL?
When MariaDB 12.3 reaches end of life, the maintainers stop issuing security patches. Any CVEs disclosed after the EOL date accumulate with no remediation path. Most vulnerability scanners do not flag this — it is the CVE blind spot. Organizations running EOL MariaDB should migrate immediately or implement compensating controls.
Does MariaDB track end-of-life by point release (e.g. MariaDB 12.3.1, MariaDB 12.3.2)?
No — MariaDB end-of-life dates apply to the entire 12.3.x release series, not individual point releases. A point release like MariaDB 12.3.1 or MariaDB 12.3.2 shares the same EOL date as MariaDB 12.3. Security patches stop for the entire 12.3.x line on that date, regardless of which patch version you are running. Check the table above for EOL dates by major version series.
