The airbrake module 0.3.8 and earlier defaults to sending environment variables over HTTP. Environment variables can often times contain secret keys and other sensitive values. A malicious user could be on the same network as a regular user and intercept all the secret keys the user is sending. This goes against common best practice, which is to use HTTPS.

Affected: npm: airbrake

Affected versions of `airbrake` default to sending environment variables over an unencrypted HTTP connection. In scenarios where an attacker has a privileged network position, it is possible for them to capture and read these environment variables, which may result in leaking sensitive information.

## Recommendation

Update to version 0.4.0 or later, or upgrade from the now-deprecated `airbrake` module to its replacement, [`airbrake-js`](https://www.npmjs.com/package/airbrake-js).
