Checking authorization against anything that isn't array|string will cause PHP errors now. The method AbstractController::denyAccessUnlessGranted() sets the given single attribute into the exception in case of denied access. The AuthorizationCheckerInterface defines that the attribute can be anything, even objects. The parameter type hint array|string of AccessDeniedException::setAttributes() want's an array of attributes (or a string for convenience).

Example

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

class MyCustomAttribute
{
}

class ProfileController extends AbstractController
{
    public function index(): Response
    {
        $this->denyAccessUnlessGranted(new MyCustomAttribute()); // 💥 ERROR: Symfony\Component\Security\Core\Exception\AccessDeniedException::setAttributes(): Argument #1 ($attributes) must be of type array|string, [...]

        $user = $this->getUser();

        return new Response('Well hi there '.$user->getFirstName());
    }
}

The fix

As the given attribute is a single attribute: always wrap it into an array when creating the exception, because the exception expects an array of attributes.

Hey!

I see that this is your first PR. That is great! Welcome!

Symfony has a contribution guide which I suggest you to read.

In short:

  • Always add tests
  • Keep backward compatibility (see https://symfony.com/bc).
  • Bug fixes must be submitted against the lowest maintained branch where they apply (see https://symfony.com/releases)
  • Features and deprecations must be submitted against the 6.3 branch.

Review the GitHub status checks of your pull request and try to solve the reported issues. If some tests are failing, try to see if they are failing because of this change.

When two Symfony core team members approve this change, it will be merged and you will become an official Symfony contributor!
If this PR is merged in a lower version branch, it will be merged up to all maintained branches within a few days.

I am going to sit back now and wait for the reviews.

Cheers!

Carsonbot

Can someone re-run the checks or something? I don't think this issue is caused by my code:

There was 1 failure:

1) Symfony\Component\Clock\Tests\MonotonicClockTest::testSleep
Failed asserting that 1677065608.00641 is equal to 1677065608.0064101 or is greater than 1677065608.0064101.

Fix AbstractController::denyAccessUnlessGranted() for attributes that aren't string or array. Always wrap the given single attribute into an array to not break the parameter type of AccessDeniedException#setAttributes() (which supports strings only for convenience).
