https://github.com/mbechler/marshalsec/blob/master/marshalsec.pdf

from the paper, we can know there are some vulnerabilities when Unmarshall hessian

https://github.com/mbechler/marshalsec

we have provided some filters in

com.caucho.hessian.io.Hessian2Input#readObjectDefinition

com.alipay.hessian.internal.InternalNameBlackListFilter is a filter which contains classes which have vulnerabilities to hacking.

what we need to do is add more classes which have vulnerabilities to the list that provided from our security team.
