Doesn't this inadvertently give users access to something they might not otherwise have? That is, the ability to add labels on issues. Might not really be a security concern, but not really desirable behaviour either.
I don't think so, it seems like its just a link to what you can see within the UI anyway and simply pre selects it for you. But I am by no means an expert on it and it is pretty simple to experiment with if you want to give it a try
