CVE-2026-63481
Hurl: Cookies in Cookies section leak when redirecting to a different host
Description
Hurl is a command line tool that runs and tests HTTP requests defined in plain text files. In version 8.0.1 and earlier, the redirect handling in packages/hurl/src/http/client.rs strips Authorization and Cookie headers and basic-auth credentials when a redirect changes host, but it carries RequestSpec.cookies created from the dedicated [Cookies] section into the redirected request. An attacker-controlled redirect can therefore receive authentication or session cookies that should remain scoped to the original host. Cookies supplied through a raw Cookie header are stripped and are not affected by this specific path. This issue is reported as fixed in version 8.1.0.

Action Type Old Value New Value Added Translation Title: hurl de Orange-OpenSource, Description: Hurl es una herramienta de línea de comandos que ejecuta y prueba solicitudes HTTP definidas en archivos de texto plano. En la versión 8.0.1 y anteriores, el manejo de redirecciones en packages/hurl/src/http/client.rs elimina los encabezados Autorización y Cookie y las credenciales de autenticación básica cuando una redirección cambia de host, pero lleva las RequestSpec.cookies creadas a partir de la sección dedicada [Cookies] a la solicitud redirigida. Una redirección controlada por un atacante puede, por lo tanto, recibir cookies de autenticación o de sesión que deberían permanecer dentro del ámbito del host original. Las cookies proporcionadas a través de un encabezado Cookie sin procesar son eliminadas y no se ven afectadas por esta ruta específica. Este problema se informa como solucionado en la versión 8.1.0. -
