Fortify Command Injection Issue in C#

Question

The method StartProcess() in WindowsApiManager.cs calls set_Arguments() to execute a command. This call might allow an attacker to inject malicious commands.

Getting the above issue while I am trying to pass file name and arguments to the start process.

I have tried with reguler expressions and path manipulation techniques but the fortify issue is still coming. If I hard code the file name and arguments to start the process then fortify issue is not coming

Please help me to resolve this.

Below is my code

var cProcess = new Process
                {
                    StartInfo =
                    {
                        FileName = sr, Arguments = arguments, WindowStyle = ProcessWindowStyle.Minimized,
                        UseShellExecute = false
                    }
                };
                cProcess.Start();
                return cProcess;
