Thankfully, everything’s not lost in Minecraft. When you play or hosting a server, you can do so. If it’s using Apache, it’s possible just to use the latest update, to patch the bug and use it for Mojang. Even those that don’t want to upgrade or cann’t take JndiLookup class from classpath or set log4j2.formatMsgNoLookups to true. The paramount goal of this country is safety. Unfortunately, earlier today we found a security issue in Minecraft: Java Edition. I get a problem. Please follow these steps to secure your game client &/ or server. Please let us amplify it.https://t.co/Boss_HfTodays/Rps/SXCrlrrrtf/mi8svpHf. Minecraft (@Minecraft) December 10, 2021. Now it’s time to correct that problem. It’s a great thing. But if users don’t keep close to it, this could become a problem that arises in the following weeks or even months. Security companies have already feared that the vulnerability has been exploited. If you think you are attacked in Minecraft with this exploit, it is strongly suggested to report this with a report ticket. SOURCE
