A vulnerability was found in cloudevents/sdk-go. This issue involves using cloudevents.WithRoundTripper to create a cloudevents.Client with an authenticated http.RoundTripper results in the go-sdk leaking credentials to arbitrary endpoints. When the transport is populated with an authenticated transport, http.DefaultClient is modified with the authenticated transport, causing it to send Authorization tokens to any endpoint it communicates with. This flaw allows an attacker to intercept and abuse these leaked credentials, potentially leading to unauthorized access to sensitive information or executing unauthorized actions on the affected system.
