It looks there is a vulnerability GHSA-hh2w-p6rv-4g7w in the System.Text.Jason version being used by the ScottPlot 4 cookbook

To fix: Remove this line and see if the project still compiles (it should, since the project now targets .NET 8). If it compiles, problem solved! If the package is still needed, use the current version from https://www.nuget.org/packages/System.Text.Json which as of today is 8.0.4
