Miggo AIRoot Cause Analysis

The vulnerability stems from improper handling of SSL/TLS close_notify messages. The SslHandler.checkStatus() method was missing CLOSED state handling, leaving sessions open. The SslFilter.messageSent() method lacked proper request wrapping to track encryption state. Both functions directly process security-critical TLS message handling and session state management. The patches explicitly modify these functions to add session closure and request wrapping logic, confirming their involvement in the vulnerability.
