Miggo AIRoot Cause Analysis

The vulnerability stems from insufficient sandboxing in the widget processing mechanism. The payload demonstrates direct access to Node.js's 'global.process' object, indicating the evaluation context isn't properly isolated. While exact file paths aren't disclosed, the core issue lies in the function evaluating widget content containing <script total> tags. This function fails to restrict access to dangerous Node.js APIs, enabling command injection via crafted JavaScript.
