Summary

Go SDK for CloudEvents's use of WithRoundTripper to create a Client leaks credentials

Details

Impact

What kind of vulnerability is it? Who is impacted? Using cloudevents.WithRoundTripper to create a cloudevents.Client with an authenticated http.RoundTripper causes the go-sdk to leak credentials to arbitrary endpoints.

The relevant code is here (also inline, emphasis added):

if p.Client == nil {
  p.Client = **http.DefaultClient**
}

if p.roundTripper != nil {
  p.Client.**Transport = p.roundTripper**
}

When the transport is populated with an authenticated transport such as:

... then http.DefaultClient is modified with the authenticated transport and will start to send Authorization tokens to any endpoint it is used to contact!
