Miggo AIRoot Cause Analysis

The commit diff shows the vulnerability was addressed by adding nonce length validation in AesGCM.Decrypt. The CWE-20 classification and Go vulnerability report (GO-2021-0102) specifically identify this function as the attack vector. Before the patch, missing length validation allowed malformed nonces to reach the cryptographic primitive, causing crashes through Go's cipher.AEAD interface which panics on invalid nonce sizes.
