Ok then,The way to do this is to implement a <whatever you actually want> event, not open a massive security hole by allowing any event to call any command.
While I agree that it's a security issue and is abusable, it's really up to the server owner, and this is likely only going to be used in mini games or with events set to admin only.
it's hard to trust players to handle their server's 'secureness'
If their server gets screwed up, it's their fault.
