MEDIUM 5.9REMOTEUPGRADE

CVE-2016-10530 is a medium-severity flaw (CVSS 5.9) affecting airbrake. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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.

Remotely exploitable, no login, no user action

A fixed release or distro patch exists.
