CVE-2024-28110 is an exposure-of-sensitive-information vulnerability in the Go SDK for CloudEvents prior to version 2.15.2. Creating a CloudEvents client with cloudevents.WithRoundTripper and an authenticated HTTP transport mutates the global http.DefaultClient to use that transport. Subsequent requests made through http.DefaultClient can therefore attach the authenticated transport's Authorization credentials when contacting endpoints unrelated to the intended CloudEvents destination.
