'dotnet restore' produces security vulnerability warnings

  • Άρθρο

The dotnet restore command, which restores the dependencies and tools of a project, now produces security vulnerability warnings by default.

Previous behavior

Previously, dotnet restore did not emit any security vulnerability warnings by default.

New behavior

If you're developing with the .NET 8 SDK or a later version, dotnet restore produces security vulnerability warnings by default for all restored projects. When you load a solution or project, or run a CI/CD script, this change might break your workflow if you have <TreatWarningsAsErrors> enabled.

Version introduced

.NET 8 Preview 4

Type of breaking change

This change is a behavioral change.

Reason for change

Many users want to know whether the packages they restore contain any known security vulnerabilities. This functionality was a highly requested feature. Security concerns continue to increase each year and some known security issues aren't visible enough to take immediate action.

  • To explicitly reduce the probability of this breaking your build due to warnings, you can consider your usage of <TreatWarningsAsErrors> and use <WarningsNotAsErrors>NU1901;NU1902;NU1903;NU1904</WarningsNotAsErrors> to ensure known security vulnerabilities are still allowed in your environment.

  • If you want to set a different security audit level, add the <NuGetAuditLevel> property to your project file with possible values of low, moderate, high, and critical.

  • If you want to ignore these warnings, you can use <NoWarn> to suppress NU1901-NU1904 warnings.

  • To disable the new behavior entirely, you can set the <NuGetAudit> project property to false.
