Questions

About Utf8Json

Is Utf8Json safe to use?

Vulert has no vulnerabilities on record for Utf8Json in NuGet 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 Utf8Json's Vulert package health score?

Vulert scores Utf8Json 67/100, 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).

Which version of Utf8Json should I use?

How often are new Utf8Json vulnerabilities disclosed?

0 vulnerabilities were recorded for Utf8Json 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.

Which versions of Utf8Json 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.
