How to Fix CVE-2023-34239

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: 3.34.0 
pip install gradio>=3.34.0
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-2023-34239, 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 3.34.0), 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. 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

### Impact There are two separate security vulnerabilities here: (1) a security vulnerability that allows users to read arbitrary files on the machines that are running shared Gradio apps (2) the ability of users to use machines that are sharing Gradio apps to proxy arbitrary URLs ### Patches Both problems have been solved, please upgrade `gradio` to `3.34.0` or higher ### Workarounds Not possible to workaround except by taking down any shared Gradio apps ### References Relevant PRs: * https://github.com/gradio-app/gradio/pull/4406 * https://github.com/gradio-app/gradio/pull/4370
