What is CVE-2026-28416?

Gradio, a popular open-source Python package for rapid prototyping, contains a Server-Side Request Forgery (SSRF) vulnerability prior to version 6.6.0. This flaw allows attackers to perform unauthorized HTTP requests from the victim's server. When users load an attacker-controlled Gradio Space using the gr.load() function, the malicious proxy_url specified in the configuration is trusted and added to the allowlist. This exploitation can grant attackers access to internal services, cloud metadata endpoints, and private networks, significantly compromising the victim’s infrastructure. Users are advised to upgrade to version 6.6.0 or later to mitigate this security risk.
