Miggo AIRoot Cause Analysis

The analysis focuses on the changes made to the SubTypeValidator class, which is directly related to the deserialization process and the mitigation of the vulnerability. The addition of 'com.sun.org.apache.xalan.internal.lib.sql.JNDIConnectionPool' to the blocklist indicates that the vulnerability involves the deserialization of this class. Thus, functions related to subtype validation are considered vulnerable or critical in mitigating the vulnerability.
