undici 是 Node.js 的 HTTP 客户端库。在版本 7.0.0 至 7.30.1 以及 8.0.0 至 8.12.3 中，重定向拦截器在请求被重定向到不同源（origin）时，会移除敏感标头（如 Authorization、Cookie、Proxy-Authorization 和 Host）。然而，当请求标头以“名称 - 值”元组数组的形式提供时（这是文档中明确支持的有效输入方式，例如通过 Object.entries 生成），重定向处理程序会错误地将其解析为扁平列表，导致标头名称无法匹配，从而未能移

Vulnerability Title
undici vulnerable to cross-origin credential disclosure via array-of-tuples headers bypassing redirect stripping
来源: CVE Program / CVE List V5
Vulnerability Description
undici is an HTTP client for Node.js. In versions 7.0.0 through 7.30.1 and 8.0.0 through 8.12.3, the redirect interceptor strips sensitive headers such as Authorization, Cookie, Proxy-Authorization, and Host when a request is redirected to a different origin, but when request headers are supplied as an array of name and value tuples (a valid documented input, for example from Object.entries), the redirect handler misreads them as a flat list so the header names never match and the sensitive headers are not removed. If a header-normalizing interceptor such as cache or deduplicate is composed outside the redirect interceptor, it then serializes the retained headers onto the cross-origin request, disclosing the caller's origin-bound credentials to the unrelated redirect destination. This is a representation-dependent bypass of the cross-origin header stripping added in CVE-2024-30260. The issue is fixed in undici 7.30.2 and 8.12.4, and users should upgrade to one of those versions or later. As a workaround, supply request headers as a plain object or a flat name and value array rather than an array of tuples, or compose the redirect interceptor outside the normalizing interceptor.
