Root 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.
