Incorrect and duplicate versions detected of a component in the same project file when using central package management (NuGet)

[Sebazzz]

I'm using Central Package Management to manage my NuGet versions centrally, and also pin subdependencies to higher versions, for instance to mitigate vulnerable transitive dependencies.

I pinned System.IdentityModel.Tokens.Jwt because it had a vulnerability, which is used by Microsoft.IdentityModel.Protocols.OpenIdConnect, which is used by Microsoft.Data.SqlClient, which is used by Microsoft.EntityFrameworkCore.SqlServer which I directly reference.

  <ItemGroup>
    <PackageVersion Include="Microsoft.Data.SqlClient" Version="5.1.4" />

    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" />
  </ItemGroup>
</Project>

I'm using the sbom-tool to generate my SBOM, and the scan manifest shows:

      "locationsFoundAt": [
        "/src/MyProject.Persistence/MyProject.Persistence.csproj"
      ],
      "component": {

            "Subpath": null

        },
        {
          "name": "Microsoft.EntityFrameworkCore.SqlServer",
          "version": "8.0.0",
          "authors": null,
          "type": "NuGet",

          "packageUrl": {

            "Version": "8.0.0",
            "Qualifiers": null,
            "Subpath": null
          }
        }
      ],
      "containerDetailIds": [],
      "containerLayerIds": {}
    },

Interestingly, in a different project in the same solution the dependency version is correctly detected, but the project mentioned above also shows up here:

 {
      "locationsFoundAt": [
        "/src/MyProject.Web/MyProject.Web.csproj",
        "/tests/MyProject.Tests.Integration/MyProject.Tests.Integration.csproj",
        "/src/MyProject.Persistence/MyProject.Persistence.csproj"
      ],
      "component": {
        "name": "System.IdentityModel.Tokens.Jwt",
        "version": "7.2.0",
        "authors": null,
        "type": "NuGet",
        "id": "System.IdentityModel.Tokens.Jwt 7.2.0 - NuGet",
        "packageUrl": {
          "Scheme": "pkg",
          "Type": "nuget",
          "Namespace": null,
          "Name": "System.IdentityModel.Tokens.Jwt",
          "Version": "7.2.0",
          "Qualifiers": null,
          "Subpath": null
        }
      }
}

We have the same issue. Does component gov not support central package management (NuGet)?

Hello @Sebazzz

I am not able to reproduce the issue. I tried your configuration using the latest version of component detection v4.2.1 and the right components are detected. I also tried running the latest version of the sbom-tool v2.2.3 and also the correct components were reported.
These are the files that I used:

csproj

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>


  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer"/>
    <PackageReference Include="Microsoft.Data.SqlClient" />
    <PackageReference Include="Newtonsoft.Json" />
  </ItemGroup>

</Project>

    <PackageVersion Include="System.IdentityModel.Tokens.Jwt" Version="7.2.0" />
    <PackageVersion Include="Newtonsoft.Json" Version="12.0.3" />
  </ItemGroup>
</Project>

This is the manifest generated by sbom
