`Curl_secure_context()` checked `conn->scheme` to determine if Secure cookies may be sent. Since73daec6, `conn->scheme` is set to the proxy's scheme when using an HTTPS forwarding proxy, causing the function to return TRUE for HTTP origins. This leaked Secure cookies over the plaintext connection between proxy and origin. Use `data->state.origin->scheme` instead, which always reflects the origin's scheme regardless of proxy configuration. Not an approved vulnerability because the regression was introduced after the last release and is not present in any released version.
