Summary

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.

Risk Assessment

The risk includes leakage of session or authentication cookies to malicious domains, potentially leading to session or account takeover. The attack requires the application to use Hurl for redirect handling and to include a [Cookies] section.

Recommendation

It is recommended to immediately upgrade to version 8.1.0 or later. Also, avoid using the [Cookies] section in redirect scenarios or manually control cookies.
