Miggo AIRoot Cause Analysis

The patch modifies the BeanDeserializerFactory class to block 'org.slf4j.ext.EventData' from polymorphic deserialization, indicating this class was previously not blocked and is now mitigated. The deserialization process, potentially handled by methods within or related to BeanDeserializerFactory, is the key area of vulnerability.
