If this famous Italian script also lets it happen, then it means the author of this famous Italian script isn't much of a scripter, because it is NOT an exploit. Why not? Read the posts and find out.
I would say that it
is an exploit. Just not an exploit of mIRC. It is an exploit of a poorly written script. But enough of splitting hairs
Any software with an advanced scripting language is capable of being taken over when someone writes poor script. mIRC is no different. I agree that this is a serious issue. It's just that I think it's an issue with the author of that script, not with Khaled. Presumably that author will either fix his script, or people will stop using it. Either way, these kinds of problems tend to go away by themselves.
