What it is

⚠️ An integer overflow in Mojang Bedrock Dedicated Server 1.18.2 could sneak past your defenses like a clever trickster! Think of it like a restaurant where the chef mistakenly thinks the kitchen can fit any size order. When someone orders a banquet for ten, the kitchen doesn't check, and voila! Too many dishes spill out everywhere, causing chaos! This could result in a sneaky bypass of checks that are supposed to keep things orderly, potentially allowing malicious packets to affect server performance or even crash it. Not ideal for maintaining a smooth gaming experience!
