Miggo AIRoot Cause Analysis

The vulnerability stems from RMI-related classes that used Java's default serialization without validation. The commit d880ffe removes all RMI transport and service implementations, including JNDIRegistration, RMIRegistration, and various RMI service classes. These functions were vulnerable because they exposed RMI endpoints that deserialized untrusted data. The removal in 3.3.10 confirms these were the attack vectors. High confidence is justified as the patch explicitly removes these RMI components to address the vulnerability.
