Questions

About asn1

Is asn1 safe to use?

Vulert has no vulnerabilities on record for asn1 in npm at this point. That is a good signal rather than a guarantee: new vulnerabilities are published for packages all the time, so the versions you actually run are still worth monitoring.

What is asn1's Vulert package health score?

Vulert scores asn1 54/100, which reads as usable, but worth attention. 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).

Is the latest version of asn1 affected?

No. 0.2.6, the version you would install today, has no vulnerabilities on record against it. Earlier releases do — the version table above lists each release with what affects it.

Which version of asn1 should I use?

0.2.6 is the version Vulert recommends for the affected releases. The version table above lists every release with the vulnerabilities recorded against it, so you can confirm the range you actually run.

How many vulnerabilities does asn1 have?

0 vulnerabilities are recorded for asn1 in the npm ecosystem: 0 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 asn1 vulnerabilities disclosed?

0 vulnerabilities were recorded for asn1 in the last 12 months. Recency matters more than a lifetime total: it shows how actively new issues are being disclosed for the package you are considering.
