Miggo AIRoot Cause Analysis

The vulnerability explicitly states the default admin password was set to the argocd-server pod name. While no exact function name is provided in the references, the core issue stems from the password initialization logic that retrieves the pod name (via Kubernetes' HOSTNAME environment variable) and uses it as the default credential. This matches CWE-1188 (insecure default initialization) and aligns with the documented mitigation requiring password changes. The confidence is high because the attack vector directly maps to this design flaw, even without seeing the exact code implementation.
