If you’ve been out the loop of ROBLOX’s Sword Fighting community (linked swords), let me introduce you to the common sight: Reach exploits
How it works:
Basically, all you do is run a short script to resize the sword’s handle and go on your merry way, killing people from miles. Now, this looks like a simple issue targeting only a portion of the community, except you can actually resize any part with a .Touched event and it will replicate server side, which means other people are also affected.
You could simply go to Natural Disaster Survival, resize one kill brick to something huge, sit back and watch as the whole server dies. Thankfully, the resized .Touched fires only once, but this is not the case for the linked sword, as it runs a touched event over and over. This is a serious security flaw and it’s been a thing for years.
This is probably the wrong section, but I cannot post it anywhere else, so here you go. This is currently unpatchable by the way.
