Miggo AIRoot Cause Analysis

The vulnerability explicitly references the CreateID function in packet.py as the source of sequential/predictable IDs. The GitHub commit shows this function was modified to use a cryptographic RNG (SystemRandom), confirming the original implementation used insecure randomness. While other parts of the code (e.g., CurrentID initialization) were also patched, the CVE description and commit focus on CreateID as the primary vulnerability vector.
