@MojangSupport There's been talk today about a potential security bug with chat messages in many Java Edition versions. However, I can't find any reliable information on this. Is this something to be concerned about? What safety precautions should be taken, if any? Thank you!

Thanks for the reply, but that's a 404 link now :/. I got to it using the wayback machine though.
