EPSS

• CVE-2024-47871: 0.18% estimated exploitation activity in the next 30 days; percentile 7.13 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact What kind of vulnerability is it? Who is impacted? This vulnerability involves insecure communication between the FRP (Fast Reverse Proxy) client and server when Gradio's share=True option is used. HTTPS is not enforced on the connection, allowing attackers to intercept and read files uploaded to the Gradio server, as well as modify responses or data sent between the client and server. This impacts users who are sharing Gradio demos publicly over the internet using share=True without proper encryption, exposing sensitive data to potential eavesdroppers. Patches Yes, please upgrade to gradio=5 to address this issue. Workarounds Is there a way for users to fix or remediate the vulnerability without upgrading? As a workaround, users can avoid using share=True in production environments and instead host their Gradio applications on servers with HTTPS enabled to ensure secure communication.

# Patch Next advisory brief: CVE-2024-47871

Advisory: Gradio uses insecure communication between the FRP client and server
IDs: CVE-2024-47871, GHSA-279j-x4gx-hfrh
Record: https://patchnext.com/advisories/cve-2024-47871 (revision 3, source checked 26 Oct 2026, 13:30 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: gradio 5.0.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI gradio: affected < 5.0.0; fixed in 5.0.0

## Suggested inspection (read-only)
- `python -m pip show gradio`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on gradio.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
