On the 9th of October, a zero-day exploit affecting Minecraft Java servers and clients using versions 1.7 to 1.18.1 was discovered. This allows malicious users to execute commands on your server without needing to be an operator, through methods such as chat, which can affect your client as well.
Mojang has released a client-sided fix that will be automatically applied by restarting your launcher. Servers however, need to be updated to the latest version, or manually secured. You can find a list of server type versions we have patched so far, or ways to secure your server type below.
