Miggo AIRoot Cause Analysis

The vulnerability stems from unsanitized cell content rendering. Since the package handles spreadsheet data display, the core cell rendering function would be responsible for outputting user-controlled values to the DOM. The provided PoC demonstrates that raw HTML/JS in cells executes when rendered, indicating the renderer doesn't sanitize outputs. While exact code isn't available, cell rendering components are the logical location for this vulnerability given the XSS through cell input description.
