Summary
Hurl: Cookies in Cookies section leak when redirecting to a different host
Details

The Bug

Hurl <= 8.0.1 lets you define cookies two ways in a .hurl file:

  1. As a raw Cookie: header in the [Header]/headers area
  2. In a dedicated [Cookies] section (parsed into RequestSpec.cookies)

When following a redirect to a different host, Hurl correctly strips security-sensitive data (Authorization, Cookie header, and basic-auth user) to avoid leaking credentials cross-host — mirroring libcurl's default behavior. But it only stripped the cookie that came in as a header. Cookies declared in the [Cookies] section were carried over to the new host unchanged — a credential-leak bug.

Hurl file that leaks cookies:

GET http://localhost:8000/follow-redirect-basic-auth?change_host=true
[Cookies]
fruit: lemon
HTTP 200

Hurl file that doesn't leak cookie:

GET http://localhost:8000/follow-redirect-basic-auth?change_host=true
Cookie: fruit=lemon
HTTP 200

Patch

With Hurl <= 8.0.1, user can use Cookie header instead of the dedicated [Cookies] section.
