In versions 2.0.0 through 2.10.4-lts, UpdateStoreTool.update_tool passes caller-supplied download_url and download_callback_url values to requests.get without equivalent trusted-host and redirect validation, allowing an authenticated workspace user to make the server request internal, loopback, link-local, or cloud metadata URLs.
