How to Fix CVE-2026-10783

To remediate this vulnerability, upgrade all affected Gradio dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

gradio fixed: 6.15.1 
pip install gradio>=6.15.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show gradio

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-10783, inspect your installed packages using pip:

pip show gradio

Analyze the terminal output to locate any version of Gradio in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.15.1), your application is affected.

Note: The pip show gradio command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-327: Use of a Broken or Risky Cryptographic Algorithm, where the product uses a broken or risky cryptographic algorithm or protocol. In Gradio, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A security flaw has been discovered in gradio-app gradio 6.14.0. This affects the function save_audio_to_cache of the component Audio Cache Key Handler. Performing a manipulation results in use of weak hash. The attack must be initiated from a local position. The attack is considered to have high complexity. It is indicated that the exploitability is difficult. The exploit has been released to the public and may be used for attacks. The patch is named 13394. To fix this issue, it is recommended to deploy a patch.
