What does Elixir end of life mean for your organization?

When a version of Elixir reaches end of life, the maintainers stop issuing security patches. Vulnerabilities discovered after this date are publicly disclosed on the National Vulnerability Database, exploit code appears on GitHub, and your systems remain permanently exposed.

The CVE blind spot: Most vulnerability scanners check for known CVEs but do not flag the accumulation of unpatched vulnerabilities in EOL software. With a zero-day, nobody knows about the vulnerability. With EOL software, the vulnerability is public — listed, rated, and often weaponized — but no patch will ever exist. This is the most dangerous gap in enterprise security posture.

Organizations running EOL Elixir should treat it as a vulnerability class in their risk register, apply compensating controls (network segmentation, enhanced monitoring, access restriction), and prioritize migration to a supported version.

Extended Support Options

If you cannot migrate immediately, extended support vendors provide continued security patches for EOL Elixir versions. This is a bridge, not a permanent solution — plan your migration in parallel.

Frequently Asked Questions

What is the end-of-life date for Elixir?

See the full table above for all Elixir version EOL dates.

When is the Elixir support end date?

Each Elixir version has its own support end date — see the table above for every version's date.

What is the latest supported version of Elixir?

The latest active version of Elixir is 1.20.1. Always verify against the table above as support windows can change.

What happens when Elixir reaches end of life?

When Elixir reaches end of life, the vendor stops issuing security patches. Any CVEs disclosed after the EOL date accumulate indefinitely with no patch path — creating an ever-growing attack surface that most vulnerability scanners do not flag.

How do I check if I'm running an EOL version of Elixir?

Check your current version against the table above. If your version's EOL date has passed, you are running unsupported software. You can also use the endoflife.ai Stack Scanner to check your entire dependency file at once.

Is there extended support available for EOL Elixir versions?

Some vendors offer extended support for EOL software. Contact the original vendor or check with enterprise support providers for options.
