FKIE_CVE-2024-1968

Vulnerability from fkie_nvd - Published: 2024-05-20 08:15 - Updated: 2025-07-15 16:01
Severity ?
7.5 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
In scrapy/scrapy, an issue was identified where the Authorization header is not removed during redirects that only change the scheme (e.g., HTTPS to HTTP) but remain within the same domain. This behavior contravenes the Fetch standard, which mandates the removal of Authorization headers in cross-origin requests when the scheme, host, or port changes. Consequently, when a redirect downgrades from HTTPS to HTTP, the Authorization header may be inadvertently exposed in plaintext, leading to potential sensitive information disclosure to unauthorized actors. The flaw is located in the _build_redirect_request function of the redirect middleware.

En consecuencia, cuando una redirecci\u00f3n degrada de HTTPS a HTTP, el encabezado de Autorizaci\u00f3n puede quedar expuesto inadvertidamente en texto sin formato, lo que lleva a una posible divulgaci\u00f3n de informaci\u00f3n confidencial a actores no autorizados. La falla se encuentra en la funci\u00f3n _build_redirect_request del middleware de redirecci\u00f3n."
