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.
