CVE-2024-47870: Gradio Project Gradio

High severity, CVSS 8.1. EPSS: 0.4% chance of exploitation in the next 30 days.

Gradio is an open-source Python package designed for quick prototyping. This vulnerability involves a **race condition** in the `update_root_in_config` function, allowing an attacker to modify the `root` URL used by the Gradio frontend to communicate with the backend. By exploiting this flaw, an attacker can redirect user traffic to a malicious server. This could lead to the interception of sensitive data such as authentication credentials or uploaded files. This impacts all users who connect to a Gradio server, especially those exposed to the internet, where malicious actors could exploit this race condition. Users are advised to upgrade to `gradio>=5` to address this issue. There are no known workarounds for this issue.
