How to fix?

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

Overview

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 Deserialization of Untrusted Data. An attacker can supply any instance of Serializable to MessagePacket and it would deserialize it without any checks. This could allow a remote attacker to execute arbitrary code if the classpath contains vulnerable serializable classes.
