Impact

The vulnerability affects the endpoint /v2/pkgs/tools/installed and the way it handles plugin names supplied as user input.
A user who has the ability to perform HTTP requests to the localhost interface, or is able to bypass the CORS configuration, can delete arbitrary files or folders belonging to the user that runs the Arduino Create Agent via a crafted HTTP POST request.
