Miggo AIRoot Cause Analysis

The vulnerability stems from the insecure use of Math.random() in the ID generation process. The commit 67b4eb9 explicitly replaces Math.random() with crypto.randomBytes in Manager.prototype.generateId, confirming this was the vulnerable function. The CWE-330 classification and advisory descriptions directly match this pattern of insufficient randomness in cryptographic identifiers.
