Moment.js vulnerabilitiesMoment.js: known vulnerabilities and safe versions

npm: moment

Moment.js has 7 known vulnerability records: 6 in the npm advisory data (GitHub Advisory Database via OSV, the same source npm audit uses) and 1 only in Retire.js (CDN builds and advisories without a CVE).

By branch: 2.x is safe from 2.31.0.

Vulnerabilities and safe version by branch

Safe version: on that branch, this release and every later one (up to the branch's latest release, where known) fall outside every known record's range. Candidates are only the records' own fixed versions and the branch's latest release; "No fix" means moving off the branch.

This page and the JavaScript library scan use the same matching rule: a row without bounds is not evidence, and versions are compared in one place. A record without a version range never counts as "affected" in the version check.
