Access check fails on user profile page

Created on 15 February 2023, over 1 year ago
Updated 21 February 2023, over 1 year ago

Problem/Motivation

The access check for a given user is missed on the user profile page due to the returned parameter being a user object. This ends up returning a "forbidden" during the access check, which removes the moderation dashboard tab from the local task menu. I would expect it to be included in the menu if the user has access.

Steps to reproduce

Visit /user/ID vs /user/ID/moderation-dashboard and observe the available links in the local tasks menu.

Proposed resolution

Extract the user id if the route parameter is an instance of a user object.

    Can you provide more info?

    Tried replicating with two different users on 2 different roles.
    going to /user/1. Moderation dashboard appears in the tasks.

    Did this on Drupal 10.1

    My user's profile page (/user/ID) returns an object as the route parameter where as the moderation page returns and id. In src/Access/ModerationDashboardAccess.php, a check against an id is done. Since I have a user object, that conditional fails for me. Drupal 10.1 as well.

    But what steps are you taking to trigger the error? I can't replicate it.

  • πŸ‡ΊπŸ‡ΈUnited States k_a_l

    Sorry, there’s no error. My user cannot access the Moderation Dashboard from the local task menu on their profile page.

    Can you verify the users permissions?

  • πŸ‡ΊπŸ‡ΈUnited States k_a_l

    The permissions for this role in question are set to: "Use the Moderation Dashboard" but not "View any Moderation Dashboard".

    I think the issue is the canonical user route has a user object parameter, while the moderation dashboard view page only has the user id.

    In the access method of src/Access/ModerationDashboardAccess.php, $current_user_id = $this->routeMatch->getParameter('user'); can either be the user object or the user id depending on the route, from what I found. As you can see in the module's Access class below, if a user object is pulled from the route, the access conditionals are not met, which ends up forbidding the local task link on the user page. See a side by side of the two different params returned from the route in Screenshot 2023-02-16 at 12.12.02 PM.png

    public function access(AccountInterface $account) {
        $dashboard_owner = $account;
        $current_user_id = $this->routeMatch->getParameter('user');
    
        // If the current user is on their own dashboard, they can view it.
        if ($current_user_id === $dashboard_owner->id() && $dashboard_owner->hasPermission('use moderation dashboard')) {
          return AccessResult::allowed();
        }
    
        // If the given user doesn't have a dashboard, nobody can view it.
        if (!$dashboard_owner->hasPermission('use moderation dashboard') && !$dashboard_owner->hasPermission('view any moderation dashboard')) {
          return AccessResult::forbidden('User does not have access to view this dashboard.');
        }
    
        // But they can only view the dashboard of others with another permission.
        if ($dashboard_owner->hasPermission('view any moderation dashboard')) {
          return AccessResult::allowed();
        }
        else {
          return AccessResult::forbidden();
        }
      }
    

    A I think a better alternative would be to use getRawParameter('user') to always pull the user id.

    Doesn't seem to break anything so I'm fine with adding it.
