Spring Boot and deserialization problem

Hi all!
So i working currently on one project where Spring Boot is in use and i read the book about Spring Boot, well during my reading i found out that Java has a huge problem with deserialization and for the fun fact i saw it actually (not in production) but at meetup ,that is possible to make a injection of byte code and execute malicious code on server , well people be aware of this problem and make sure you take all your time to catch such "bad behavior" of Java.......
