Is webpack healthy, maintained, and safe?
No — webpack carries 1 unpatched critical advisory and should not be adopted without a remediation plan.
The verdict
OSPulse scores webpack at 55/100 (medium risk), computed deterministically from live npm release history, maintainer data, and the OSV vulnerability database. No — webpack carries 1 unpatched critical advisory and should not be adopted without a remediation plan.
Its most recent release shipped on 23 July 2026 — 3 days ago — so development is clearly active. Across 885 releases the cadence has been steady, which is a good sign of an ongoing maintenance rhythm. 8 maintainers are listed on npm, so the project isn't hostage to any single contributor.
OSV lists 4 known advisories for webpack, including 1 critical. 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.
webpack 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. Run your own package.json through the free health check, or have OSPulse monitor your whole dependency tree continuously.
