Spring Security 6.4 left standard support on 31 Dec 2025. It still receives security updates under extended support until 31 Dec 2026 — 144 days from now — but only if you are enrolled. Without it, no fixes reach you.
Can I still download Spring Security 6.4?
Yes — the final release (6.4.13) generally remains available from vendor archives and OS package mirrors, but installing it means running software with known, unpatched vulnerabilities.

Upgrade to Spring Security 7.1, the newest actively supported branch (supported until 31 Jul 2027).
