Next.js 12 End of Life Date
Next.js 12 end-of-life date, support status, and CVE risk. Data reconciled from official vendor documentation and endoflife.date at every build; the source of each date is on the product page.
Next.js 12 was released on October 26, 2021 and support ended on November 21, 2022 — a supported lifespan of 1 year and 1 month, shorter than the 1 year and 4 months median for Next.js releases. It was not an LTS release; Next.js reserves longer patch windows for its LTS releases. Its latest release on record is 12.3.7, published March 28, 2025 — 2 years and 4 months after the published end-of-life date. It has been past its end-of-life date for 4 years. 3 newer Next.js releases have shipped since.
Extended support for Next.js exists: vetted vendors ship security patches past the official date. Right now that coverage spans Next.js 12.3.5, with 10+ post-EOL CVE fixes documented in vendor release notes. Whether it covers Next.js 12 is part of what we check. Leave an email and we reply within one business day with matched options and pricing guidance, or an honest "no vendor covers this version." Free, no obligation; vendors do not pay for placement.
What does Next.js 12 end of life mean?
When Next.js 12 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: A CVE-based scan does not show the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Some scanners flag unsupported versions of common products, but coverage varies, and none of them give you the date in advance. Running Next.js 12 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to Next.js 16 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
