| 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. | |
