TYPO3 12 left standard support on 30 Apr 2026. It still receives security updates under extended support until 30 Apr 2029 — 995 days from now — but only if you are enrolled. Without it, no fixes reach you.
Can I still download TYPO3 12?

Upgrade to TYPO3 14, the newest actively supported branch (supported until 30 Jun 2029).
