GHSA-745p-r637-7vvp

### Impact
Setting `$secure` or `$httponly` value to `true` in `Config\Cookie` is not reflected in `set_cookie()` or `Response::setCookie()`.

> **Note**
> This vulnerability does not affect session cookies.

The following code does not issue a cookie with the secure flag even if you set `$secure = true` in `Config\Cookie`.

```php
helper('cookie');

$cookie = [
'name' => $name,
'value' => $value,
];
set_cookie($cookie);
// or
$this->response->setCookie($cookie);
```

### Patches
Upgrade to v4.2.7 or later.

### Workarounds
1. Specify the options explicitly.
```php
helper('cookie');

$cookie = [
'name' => $name,
'value' => $value,
'secure' => true,
'httponly' => true,
];
set_cookie($cookie);
// or
$this->response->setCookie($cookie);
```
2. Use Cookie object.
```php
use CodeIgniter\Cookie\Cookie;

helper('cookie');

$cookie = new Cookie($name, $value);
set_cookie($cookie);
// or
$this->response->setCookie($cookie);
```
