The package com.h2database:h2 from 1.4.198 and before 2.0.202 are
vulnerable to XML External Entity (XXE) Injection via the
org.h2.jdbc.JdbcSQLXML class object, when it receives parsed string data
from org.h2.jdbc.JdbcResultSet.getSQLXML() method. If it executes the
getSource() method when the parameter is DOMSource.class it will trigger
the vulnerability.
