Consequently, a\nmalicious server can trigger a redirect containing arbitrary userinfo to force\ncurl to send a freshly minted Kerberos ticket—generated using the ambient\nidentity of the client process to an untrusted third-party host, effectively\nbypassing the domain-scoping restrictions normally enforced by the absence of\n`--location-trusted`."
