Miggo AIRoot Cause Analysis

The vulnerability stems from unescaped network name rendering in horizon.instances.js. The commit diff shows the fix added HTML entity escaping (e.g., replacing & with &, < with <). The original code used raw network name text from DOM elements (name: $this.text().replace(/^\s+/, "")), making it vulnerable. This matches the CVE description of XSS via network names.
