I tried to boot the game with the 1.8.0_60 version, and this is the output I found in the log.
[01:30:26] [Client thread/INFO] [log4j-vulnerability-detector/gregapi]: Checking if the log4j Exploit has been fixed.
[01:30:26] [Client thread/INFO] [log4j-vulnerability-detector/gregapi]: If the Game Crashes from this following check there are a few ways to fix it:
[01:30:26] [Client thread/INFO] [log4j-vulnerability-detector/gregapi]: 1. Update Java to one of the following Versions or later: Java 7 – 7u202+, Java 8 – 8u192+, or whichever Java equivalent you use that has the log4j exploit fixed. Yes, Oracle fixed this exploit back in 2018 already.
[01:30:26] [Client thread/INFO] [log4j-vulnerability-detector/gregapi]: 2. Use a Minecraft Launcher that automatically updates log4j for you to a patched Version, such as the official Launcher or MultiMC
[01:30:26] [Client thread/INFO] [log4j-vulnerability-detector/gregapi]: 3. Install one of the many Patcher Mods that fix this Issue in one way or another.
[01:30:26] [Client thread/INFO] [log4j-vulnerability-detector/gregapi]: Now performing the actual check! Don't worry, these are IPs which loop back to your own Computer, and dont go to your Network!

It looks like the detection didn’t work, I entered the detection in the game and crashed.
Maybe it’s better to test it yourself. https://drive.google.com/file/d/1zR6bTh8Fyce3Oiy0zLpCiBkJCHVYJgAl (
