The solution is that an intruder must breach the server network and either discover the app secret or intercept the network traffic from the server to Google (which is secured by HTTPS) in order to acquire the access token if they wish to steal user access tokens from an application using code flow. In order to give users more control over files without granting root access, ACLs are used.
