Details

### Summary

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.

### Patches [This patch](https://github.com/wojtekmaj/react-pdf/commit/671e6eaa2e373e404040c13cc6b668fe39839cad) forces `isEvalSupported` to `false`, removing the attack vector.

### Workarounds Set `options.isEvalSupported` to `false`, where `options` is `Document` component prop.
