What is CVE-2024-45336?

A vulnerability in the Go HTTP client allows sensitive headers to be dropped when following cross-domain redirects. Specifically, when the HTTP client is redirected from one domain to another, it does not send sensitive headers, such as the Authorization header, to the second domain. However, if the client follows a sequence of redirects that remain within the same domain, these sensitive headers are incorrectly restored and sent to subsequent requests within that domain. This behavior can lead to unintended exposure of sensitive information.
