webrtc-native uses WebRTC from chromium project. webrtc-native downloads binary resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested binary with an attacker controlled binary if the attacker is on the network or positioned in between the user and the remote server.

Affected: npm: webrtc-native

Affected versions of `webrtc-native` insecurely download an executable over an unencrypted HTTP connection.

In scenarios where an attacker has a privileged network position, it is possible to intercept the response and replace the executable with a malicious one, resulting in code execution on the system running `webrtc-native`.

## Recommendation

No direct patch is currently available for this vulnerability.

However, if the native components of `webrtc-native` are built from source, this avoids download the precompiled binary, therefore mitigating the insecure download.

The package author has provided instructions for building from source [here](https://github.com/vmolsa/webrtc-native/wiki/Getting-started#building-from-source).
