This is a huge confidentiality breach. We have one workspace for our company, and separate spaces for individual clients. The clients noticed that when they are in their own space and they want to tag someone, they type @ and the names that come up automatically are users outside of their organization. it starts displaying names and email addresses of all our workspace members in alphabetical order. if you start typing it narrows it down to match your search, but it will still show all members that match that search criteria even if they don't have access to the space. It's one thing if you want to give that ability to admins and they can add someone to a task that way, but for any user to be able to see this is a huge confidentiality breach. I've contacted support and they say they are aware of this and are working on it, but this needs to be a priority so that it gets fixed ASAP. I already had 2 separate clients notice this. It is beyond unprofessional and I can't even tell them when it will be fixed. Apparently it might be weeks or even months according to support. Lets upvote this and get it on their radar please!
