CVE-2026-48022 | @hapi/wreck: Sensitive credential headers leak across cross-port and cross-scheme redirects

@hapi/wreck is an HTTP client utility. Prior to 18.1.2, Wreck strips credential headers including Authorization, Cookie, and Proxy-Authorization before following a cross-origin redirect, but the origin check compares hostnames only and ignores scheme and port, so credentials are forwarded intact across same-host port changes and HTTPS-to-HTTP downgrades, allowing a co-tenant on an adjacent port or a network-position attacker capable of forging a redirect to capture bearer tokens, session cookies, and proxy credentials and impersonate the victim against the upstream service. This issue is fixed in version 18.1.2.
