CVE-2026-59806

Gradio before 6.20.0 contains an open redirect and server-side request forgery vulnerability that allows attackers to redirect users to arbitrary URLs or perform client-side SSRF by supplying unvalidated HTTP/HTTPS URLs to the file_fetch() function in the /gradio_api/file= endpoint. Attackers can craft a malicious FileData response targeting internal endpoints such as cloud metadata services to retrieve sensitive credentials including EC2 IAM role credentials.

Summary		(es) Gradio anterior a la versión 6.20.0 contiene una vulnerabilidad de redirección abierta y de falsificación de petición del lado del servidor que permite a los atacantes redirigir a los usuarios a URL arbitrarias o realizar SSRF del lado del cliente al proporcionar URL HTTP/HTTPS no validadas a la función file_fetch() en el endpoint /gradio_api/file=. Los atacantes pueden elaborar una respuesta FileData maliciosa dirigida a endpoints internos, como servicios de metadatos en la nube, para recuperar credenciales sensibles, incluyendo credenciales de rol IAM de EC2.
