# CVE-2024-4367 & CVE-2024-34342: Arbitrary JavaScript execution in PDF.js

A type check was missing when handling fonts in PDF.js, which would allow arbitrary JavaScript execution in the PDF.js context. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11.

If pdf.js is used to load a malicious PDF, and PDF.js is configured with isEvalSupported set to true (which is the default value), unrestricted attacker-controlled JavaScript will be executed in the context of the hosting domain.

- JS Execution
```
python3 CVE-2024-4367.py "alert(document.domain)"
```

```
