CVE-2024-1561Public exploitNetwork attack vector

Arbitrary file read via unrestricted component methods

Published Apr 16, 2024 · Updated Feb 13, 2025

Path traversal in Gradio before 4.13.0 allows remote attackers to read arbitrary host files through the component server endpoint. The /component_server route resolves attacker-controlled fn_name values with getattr() and invokes the resulting Block method without requiring its _is_server_fn marker. No authentication or user interaction is required when the application is network-reachable; retrieved files can disclose host secrets, including API keys and credentials.
