Miggo AIRoot Cause Analysis

The vulnerability stemmed from the debug flag enabling TLD validation bypass (require_tld: !debug). This allowed local/internal URLs when debug=true (default in vulnerable versions). The functions validateURL(), meta, and get() in url.js used this flag to weaken security checks, enabling SSRF and internal network probing. The patch replaced debug with allowLocalUrls (default false) and hardened TLD validation.
