Is mongoose healthy, maintained, and safe?
No — mongoose carries 4 unpatched critical advisories and should not be adopted without a remediation plan.
The verdict
OSPulse scores mongoose at 55/100 (medium risk), computed deterministically from live npm release history, maintainer data, and the OSV vulnerability database. No — mongoose carries 4 unpatched critical advisories and should not be adopted without a remediation plan.
Its most recent release shipped on 27 July 2026 — 1 days ago — so development is clearly active. Across 1019 releases the cadence has been steady, which is a good sign of an ongoing maintenance rhythm. 3 maintainers are listed on npm, so the project isn't hostage to any single contributor.
OSV lists 9 known advisories for mongoose, including 4 critical and 3 high. Open critical advisories are the strongest possible signal to pin to a patched version, replace, or fork before shipping. Each advisory is listed with its OSV/GHSA identifier below.
mongoose is usable but carries real signals — pin versions, watch for new advisories, and keep a fallback in mind. This is a one-time snapshot of a single package — real projects depend on dozens or hundreds of packages, and any one of them can drift or be compromised between releases.
