Security vulnerabilities should not be reported as an issue on github because anyone can see this issue and use it.
On the other hand, Security vulnerabilities should be reported as fast as possible.
You can report vulnerabilities on the GitHub security tab or send a private message to the Bot Owner ShowMeYourSkil#5698.
Private Messages are only allowed if users are member of a common server (Guild). In order to bypass that you can join Progen's Support Guild.
