CVE-2023-41626: Gradio arbitrary file upload vulnerability

The vulnerability explicitly references the /upload interface as the attack vector. In web frameworks like Gradio, route handlers are typically mapped to specific functions. The combination of CWE-434 (unrestricted file upload) and the advisory's description of temporary directory uploads points to the file upload handler function as the vulnerable component. While exact code isn't available, Gradio's architecture patterns and the vulnerability description strongly suggest the upload_file route handler in routes.py is responsible for insecure file handling.
