CVE-2024-47870

Gradio has a race condition in updaterootin_config may redirect user traffic

What kind of vulnerability is it? Who is impacted?

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.

Multiple concurrent operations access a shared resource without proper synchronization, producing unpredictable results depending on timing. Typical impact: TOCTOU exploits, data corruption, or privilege escalation.

CVE-2024-47870 has a CVSS score of 7.0 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (5.0.0); upgrading removes the vulnerable code path.

1. What is CVE-2024-47870? CVE-2024-47870 is a high-severity race condition vulnerability in gradio (pip), affecting versions < 5.0.0. It is fixed in 5.0.0. Multiple concurrent operations access a shared resource without proper synchronization, producing unpredictable results depending on timing.
2. How severe is CVE-2024-47870? CVE-2024-47870 has a CVSS score of 7.0 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of gradio are affected by CVE-2024-47870? gradio (pip) versions < 5.0.0 is affected.
4. Is there a fix for CVE-2024-47870? Yes. CVE-2024-47870 is fixed in 5.0.0. Upgrade to this version or later.
5. Is CVE-2024-47870 exploitable, and should I be worried? Whether CVE-2024-47870 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2024-47870 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2024-47870? Upgrade gradio to 5.0.0 or later.
