Arduino Create Agent path traversal - local privilege escalation vulnerability

The vulnerability affects the endpoint /upload which handles request with the filename parameter. A user who has the ability to perform HTTP requests to the localhost interface, or is able to bypass the CORS configuration, can escalate his privileges to those of the user running the Arduino Create Agent service via a crafted HTTP POST request.
