Critical vulnerability has been closed - exploit has been fixed

This version fixes an extremely critical bug! Please update to Bungee/Waterfall! This update fixes a security vulnerability that allowed the Voxel Hack Client to execute any command on the proxy if the T2CodeLib was installed on it (https://github.com/Renovsk/VoxelClient-SRC/blob/main/me/nullnet/voxelclient/exploits/T2CExploit.java). This has been fixed. This has been fixed and all games that try to use this exploit are now displayed in the console. Translated with www.DeepL.com/Translator (free version)

JaTiTV	fccf878b81	Critical vulnerability has been closed - exploit has been fixed This version fixes an extremely critical bug! Please update to Bungee/Waterfall! This update fixes a security vulnerability that allowed the Voxel Hack Client to execute any command on the proxy if the T2CodeLib was installed on it (https://github.com/Renovsk/VoxelClient-SRC/blob/main/me/nullnet/voxelclient/exploits/T2CExploit.java). This has been fixed. This has been fixed and all games that try to use this exploit are now displayed in the console.
