CVE-2024-4940Network attack vector

User redirection via improperly validated URLs

Published Jun 22, 2024 · Updated Oct 15, 2025

Open redirect in Gradio 4.36.1 and earlier allows remote attackers to send users to attacker-controlled sites via crafted URLs. Published records identify improper URL validation but do not name the affected route or function that accepts and redirects the URL. Exploitation requires a user to follow the crafted link; the demonstrated consequence is redirection that can support phishing.
