Exploit using "add_player" and "move_player" Packets

I’ve recently been informed about an exploit that allows online players to extract NBT information, such as another player’s Bed Position and teleportation coordinates, from packets.

Unfortunately, I don’t have the means to test this script myself, as I only have one file and not the entire script structure. However, players who are allegedly using this program have indeed been able to locate countless private bases on the public survival realm I manage. This leads me to believe that the exploit is genuine.

I understand this isn’t a typical bug report, but I have no other way to convey these concerns to you. I would sincerely appreciate it if you could look into this matter and inform me whether I should be concerned about this exploit.

See attachment bellow to inspect the alleged script file used for this exploit and how it functions.
