How to Fix GHSA-4m3g-6r7g-jv4f

To remediate this vulnerability, upgrade all affected Gradio pdf 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_pdf fixed: 0.0.10 
pip install gradio_pdf>=0.0.10
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_pdf

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-4m3g-6r7g-jv4f, inspect your installed packages using pip:

pip show gradio_pdf

Analyze the terminal output to locate any version of Gradio pdf in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.10), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Gradio pdf, 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

### Summary gradio-pdf projects with dependencies on the pdf.js library are vulnerable to CVE-2024-4367, which allows arbitrary JavaScript execution. ### PoC 1. Generate a pdf file with a malicious script in the fontmatrix. (This will run `alert(‘XSS’)`.) [poc.pdf](https://github.com/user-attachments/files/15516798/poc.pdf) 2. Run the app. In this PoC, I've used the demo for a simple proof. ![1](https://github.com/freddyaboulton/gradio-pdf/assets/114328108/d1bb7626-3d0f-4984-8873-297658d6e77e) 3. Upload a PDF file containing the script. ![2](https://github.com/freddyaboulton/gradio-pdf/assets/114328108/803d8080-c946-446e-bb34-cf5640e1b4de) 4. Check that the script is running. ![3](https://github.com/freddyaboulton/gradio-pdf/assets/114328108/4956b95f-acca-4bb1-a3c2-7dfc96adf890) ### Impact Malicious scripts can be injected into the code, and when linked with vulnerabilities such as CSRF, it can cause even greater damage. In particular, It can become a source of further attacks, especially when linked to social engineering. ### Mitigation Upgrade the pdf.js to v4.2.67, which removes the vulnerability. (or set the option `isEvalSupported` to `false`.) ### Reference 1. https://codeanlabs.com/blog/research/cve-2024-4367-arbitrary-js-execution-in-pdf-js/ 2. https://github.com/mozilla/pdf.js/pull/18015
