How to fix?

Upgrade de.gurkenlabs:litiengine to version 0.5.1 or higher.


de.gurkenlabs:litiengine is a pure 2D free java game engine. Written in plain Java 8 it provides all the infrastructure to create a 2D tile based java game, be it a platformer or a top-down adventure.

Affected versions of this package are vulnerable to Improper Input Validation. The validate method of litiengine/src/de/gurkenlabs/litiengine/net/messages/ is not abstract. This means that a subclass of ClientMessage will accept any message (as long as it's not null) by default if the developer forgets to implement validate.
