In gradio <=4.42.0, the gr.DownloadButton function has a hidden server-side request forgery (SSRF) vulnerability. The reason is that within the save_url_to_cache function, there are no restrictions on the URL, which allows access to local target resources. This can lead to the download of local resources and sensitive information.
