  "details": "### Impact\nWhen `@hapi/wreck` follows a 3xx redirect to a different hostname, only the `Authorization` and `Cookie` headers are stripped. The standard credential header `Proxy-Authorization` is forwarded intact to the redirect target, potentially exposing forward-proxy credentials to a host outside the original trust boundary.\n\nRedirect following is opt-in. The redirects option defaults to false (no redirections followed), so applications are only affected if they have explicitly set redirects to a positive integer on the request or via `Wreck.defaults({ redirects: ... })`.\n\n### Patches\n`@hapi/wreck` 18.1.1 extends the cross-hostname strip set to include `proxy-authorization`. Upgrade to 18.1.1 or later.\n\n### Workarounds\nIf upgrading is not immediately possible:\n- Leave redirects at its default (`false`) \u2014 applications that never enable redirect following are not affected.\n- If redirects are required, set redirects: 0 when calling endpoints with sensitive headers, or strip Proxy-Authorization from the headers before issuing the request.\n- Use the `beforeRedirect` hook to manually strip proxy-authorization (and any other sensitive application headers) when `redirectOptions` targets a different hostname than the original request.\n\n### Resources\n- Related: [CVE-2024-30260 / GHSA-3787-6prv-h9w3 ](https://github.com/nodejs/undici/security/advisories/GHSA-3787-6prv-h9w3)(undici)\n- [RFC 7235 \u00a74.4 \u2014 Proxy-Authorization](https://datatracker.ietf.org/doc/html/rfc7235#section-4.4)",
