AWS Lambda Java 21 End of Life Date
AWS Lambda Java 21 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.
AWS Lambda java21 was released on November 17, 2023 and support is scheduled to end on August 31, 2029 — a planned supported lifespan of 5 years and 10 months, longer than the 3 years and 10 months median for AWS Lambda releases.

What does AWS Lambda Java 21 end of life mean?
When AWS Lambda Java 21 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 AWS Lambda Java 21 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to AWS Lambda Java 17 (AL2023) or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
