Miggo AIRoot Cause Analysis

The vulnerability stems from improper authentication in the ZEO network protocol. The ZEO storage server's handshake process (handle_zeo_handshake) is the critical point where client authentication is negotiated. Pre-3.8.2 versions lacked proper validation of authentication credentials during this phase, as evidenced by the CWE-287 classification and the advisory's focus on ZEO protocol vectors. The function's role in the authentication workflow and the patched version's requirement (3.8.2) strongly indicate this as the vulnerable component.
