SameSite cookies

image

Same-site cookies ("First-Party-Only" or "First-Party") allow servers to mitigate the risk of CSRF and information leakage attacks by asserting that a particular cookie should only be sent with requests initiated from the same registrable domain.

Warning: SameSite cookies doesn't work at all for old Browsers and also not for some Mobil Browsers e.g. IE 10, Blackberry, Opera Mini, IE Mobile, UC Browser for Android.

Slim 4 integration

<?php

use Selective\SameSiteCookie\SameSiteCookieMiddleware;
use Slim\Factory\AppFactory;

$app = AppFactory::create();

// ...

// Register the samesite cookie middleware
$app->add(new SameSiteCookieMiddleware());

// ...

$app->run();

Example with configuration and the session starter middleware.

Slim 4 uses a LIFO (last in, first out) middleware stack, so we have to add the middleware in reverse order:

<?php

use Selective\SameSiteCookie\SameSiteCookieConfiguration;
use Selective\SameSiteCookie\SameSiteCookieMiddleware;
use Selective\SameSiteCookie\SameSiteSessionMiddleware;
use Slim\Factory\AppFactory;

$app = AppFactory::create();

// ...

// Optional: Add custom configuration
$configuration = new SameSiteCookieConfiguration();

// Register the samesite cookie middleware
$app->add(new SameSiteCookieMiddleware($configuration));

// Optional: Start the PHP session
// Use this middleware only if you have no other session starter middleware
$app->add(new SameSiteSessionMiddleware());

// ...

$app->run();
