You may be reading reports in the news of a new software vulnerability nicknamed ‘Log4Shell’. It affects a software component, Log4j2 that manages logging for Java applications. Lamplight isn’t written in Java and so does not use this application directly; and the version on our servers (used by some server management tools) is not affected by the issue.
Lamplight servers update themselves daily with the latest updates. The strong advice is to make sure your machines, software and devices are too, at home and at work. Apparently this ‘Log4Shell’ vulnerability is present in Minecraft, and your machine can be taken over by someone sending you an in-game chat message.
