Why?

The developer of this project was too lazy to type their complicated password every time they wanted to execute privileged user operations.

Isn't this unsafe?

That's why the group barrier was added. Only users in a certain group get read/write access to the named pipe. This prevents other users from using privileged user operations without a password.

Do you realize this program creates a serious vulnerability in your system?

I do, yes. However, I need it badly. whenever I use sudo, I always get the password wrong 7-9 times. I didn't want to resort to this but I am left with no choice.
