These puzzles are generated by GPT4 and some may seem nonsensical or disclose the answer within the code itself. I am still working on those issues and doing my best to improve the code generation!

Can you spot the vulnerability?

csharp
using System.IO;

class Program
{
    static void Main()
    {
        string fileName = "sensitive_data.txt";
        FileStream fileStream = File.Create(fileName);
    }
}
