elliptic End of Life (EOL) Dates & Support Timeline
Complete end-of-life dates, support windows, and security status for all elliptic versions. Data sourced from endoflife.date and official vendor documentation. Updated at every deploy.
| Version | Latest Release | Release Date | EOL Date | Days | Status |
|---|---|---|---|---|---|
| 6 | 6.6.1 | Oct 28, 2015 | TBD | Supported | Active |
elliptic lifecycle status — the real story
elliptic implements elliptic-curve cryptography in pure JavaScript and sits, mostly invisibly, under a large share of the browser-crypto and blockchain tooling ecosystem — bundled via webpack's node-polyfills, crypto-browserify, and countless wallet libraries. Cryptographic primitives are an unforgiving place for lifecycle risk.
The 6.x line has been current since 2015; maintenance is sparse but responsive to disclosures — the 6.6.x releases of late 2024 addressed signature-verification flaws. No end of life has been declared, but there is no formal support policy either: fixes arrive when researchers find problems and the maintainer responds.
Because elliptic almost always arrives transitively, most affected applications don't know they ship it. Lockfile-level auditing and prompt uptake of new 6.6.x+ releases are the practical mitigations.
What does elliptic end of life mean for your organization?
When a version of elliptic 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 elliptic 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 elliptic versions. This is a bridge, not a permanent solution — plan your migration in parallel.
