Miggo AIRoot Cause Analysis

The patch directly modifies the SubTypeValidator class, indicating that the vulnerability is related to the handling of subtypes during deserialization. The addition of 'br.com.anteros.dbcp.AnterosDBCPDataSource' to the blocked list suggests that this class was previously not blocked and could be exploited.
