This plugin only fix server side, if you need to fix for clients please consider my other plugin ProtocolStringReplacer, which includes this fix for console. You must download and install the example replacerconfig in that thread.

The plugin is an independent version from ProtocolStringReplacer.

Can defend Log4j Jndi vulnerability for all servers
This solution is similar to Spigot / Paper (replace the Jndi plugin).
Can prevent all logs, including chat, commands, plugins and so on!
Support whitelisting (although it is useless)
The modification to the server is minimal, but the effect is vividly reflected
