https://github.com/erlang/otp/security/advisories/GHSA-m75x-4vwg-ggjh reports:

The HTTP client (httpc) in inets now removes Authorization, Proxy-Authorization, Cookie, Referer, and Origin headers when following a redirect to a different host or port, following the requirements of RFC 9110 section 15.4. Previously these headers were forwarded verbatim, potentially leaking credentials to unintended targets.
