Miggo AIRoot Cause Analysis

The vulnerability stems from unescaped template rendering in typeahead components. The patch (PR #4904) specifically adds _.escape() calls to sanitize suggestion values in TypeAheadInput.jsx. Both components mentioned in the advisory handle user-controlled input for search suggestions without proper output encoding in vulnerable versions. The XSS occurs because user input was directly rendered in HTML templates without sanitization, allowing script execution when suggestions were displayed.
