Questions

About napi-postinstall

Is napi-postinstall safe to use?

No. Vulert records a malicious-package vulnerability for napi-postinstall: a published version contained hostile code rather than a bug, and the package looks like one that was withdrawn for abuse. Do not install it, and check whether it is already resolved in your dependencies.

What is napi-postinstall's Vulert package health score?

Vulert scores napi-postinstall 15/100, which reads as critical. The score weighs the vulnerability record (40), maintenance and release cadence (25), adoption from dependents and stars (20) and community signals such as the OpenSSF scorecard and forks (15). The current release contains malicious code, which caps this score.

Is the latest version of napi-postinstall affected?

Yes. 0.3.7, the version you would install today, has 1 known vulnerability, and 1 has no published fix yet. Use an earlier unaffected release, or the workaround each vulnerability lists.

How many vulnerabilities does napi-postinstall have?

1 vulnerability is recorded for napi-postinstall in the npm ecosystem: 1 critical, 0 high, 0 medium and 0 low. The ledger on this page lists the same counts next to the date of the most recent disclosure.

How often are new napi-postinstall vulnerabilities disclosed?

0 vulnerabilities were recorded for napi-postinstall in the last 12 months, and the oldest entry in this database dates to 21 Jul 2025. Recency matters more than a lifetime total: it shows how actively new issues are being disclosed for the package you are considering.

Which versions of napi-postinstall are affected?

Each vulnerability on this page lists the affected version range and the fixed version to move to. Open the vulnerability for the version you actually run — fixes are specific to a release line, not to the package as a whole.

What does a malicious-package vulnerability mean?

It means the published package itself contained hostile code — a backdoor, a credential stealer or similar — rather than only a bug. Registries remove such packages once they are confirmed, so treat any application that resolved an affected version as compromised and rotate the credentials it could reach.

How do I monitor napi-postinstall for upcoming vulnerabilities?

Upload the manifest or SBOM for your application at vulert.com/scanner and Vulert keeps checking the napi-postinstall version you actually run against new disclosures, then alerts you when one affects it. There is no installation and no source-code access required.
