As of 7 March 2025, the FlareSolverrSharp package installs System.Net.Http 4.3.0, which should be updated to 4.3.4.
Also System.Text.RegularExpressions 4.3.0 should be updated to 4.3.1.
Visual Studio says the lower versions have high severity vulnerabilities.
Of course, we can update our own local systems. I have not tried, I am trying to get FSS to work as installed, then update the system references.
Thanks for your work.
