    LOW
    // summary

    gradio-pdf projects with dependencies on the pdf.js library are vulnerable to CVE-2024-4367, which allows arbitrary JavaScript execution.

    // poc
    • Generate a pdf file with a malicious script in the fontmatrix. (This will run alert(‘XSS’).)

    poc.pdf

    • Run the app. In this PoC, I've used the demo for a simple proof.
    • Upload a PDF file containing the script.
    • Check that the script is running.
    // 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.)
