Moment.js lifecycle status — the real story
Moment.js formally declared itself a legacy project in maintenance mode in September 2020 — one of the clearest end-of-active-development statements in open source. The maintainers committed to no new features, no version 3, and no major changes; only critical security fixes and IANA timezone-data updates for Moment-Timezone continue. The last release, 2.30.1, shipped in December 2023.
Despite that, Moment still sees on the order of 14 million weekly downloads — almost entirely legacy dependency chains. The maintainers themselves recommend Day.js, date-fns, Luxon, or the native Intl APIs for new work, and Moment's mutable API and bundle size are the usual migration motivations beyond lifecycle risk.
For risk assessment, treat Moment as stable-but-frozen: it is not abandoned, but any newly discovered vulnerability outside the "critical" bar may never be patched, and the project's own guidance is to migrate.
What does Moment.js end of life mean for your organization?
When a version of Moment.js 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 Moment.js 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 Moment.js versions. This is a bridge, not a permanent solution — plan your migration in parallel.
