CyberRota Analysis
AI-GeneratedThe vulnerability in urllib allows for the unintended reuse of authentication headers and sensitive options when following redirects to different origins, potentially exposing credentials to attacker-controlled destinations. This could lead to unauthorized access to APIs and related services without requiring user interaction. Organizations using affected versions should prioritize updating to versions 2.44.1 or 4.9.1 to mitigate the risk of credential leakage.

Original NVD Description
urllib is an HTTP client for Node.js that supports authentication, redirects, timeouts, and other request features. Prior to 4.9.1 and 2.44.1, urllib follows redirects through followRedirect but reuses caller-supplied options across origins. In src/HttpClient.ts, #requestInternal recursively calls this.#requestInternal(nextUrl.href, options, requestContext), causing options.headers and auth or digestAuth values to be reused when the redirect target has a different scheme, host, or port. Authorization, Cookie, Proxy-Authorization, x-api-key, x-auth-token, and x-access-token can therefore be sent to an attacker-controlled redirected origin, exposing credentials intended for the original origin and potentially allowing reuse against the original partner API or related services. No user interaction is required. This issue is fixed in versions 2.44.1 and 4.9.1.
