Miggo AIRoot Cause Analysis

The vulnerability stemmed from two key issues: 1) GetHTMLMeta used http.Get(), which follows redirects by default without validating intermediate URLs. Attackers could exploit this by chaining redirects to internal endpoints. 2) The original validateURL function only checked the initial host's IP, not resolved IPs from DNS queries. The commit f17774cb introduced a custom HTTP client with redirect validation and enhanced DNS-based IP checks, confirming these were the missing safeguards.
