What does Spring Boot 4.0 end of life mean?
When Spring Boot 4.0 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 Spring Boot 4.0 past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.
Migrate to Spring Boot 4.1 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
Frequently Asked Questions

Spring Boot full timeline for all supported versions.
What are the security risks of running Spring Boot 4.0 past EOL?
When Spring Boot 4.0 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 Spring Boot should migrate immediately or implement compensating controls.
Does Spring Boot track end-of-life by point release (e.g. Spring Boot 4.1.1, Spring Boot 4.1.2)?
No — Spring Boot end-of-life dates apply to the entire 4.1.x release series, not individual point releases. A point release like Spring Boot 4.1.1 or Spring Boot 4.1.2 shares the same EOL date as Spring Boot 4.1. Security patches stop for the entire 4.1.x line on that date, regardless of which patch version you are running. Check the table above for EOL dates by major version series.
