CVE-2024-47165Network attack vector

Data theft via trusted null CORS origin

Published Oct 10, 2024 · Updated Oct 11, 2024

Improper authorization in Gradio before 5.0 allows remote attackers to read authentication tokens or uploaded files via a null origin. The server's localhost_aliases list treats the literal null origin as trusted during CORS validation. A locally deployed server must receive a request from a sandboxed iframe or another source that sends a null Origin header; basic authentication increases exposure.
