Technical details
An improper authorization vulnerability (CWE-285) exists in Craft CMS versions 4.x prior to 4.18.1. The 'actionReorderSets' function within 'src/controllers/GlobalsController.php' failed to enforce administrative privilege checks. A remote attacker with low-level authenticated access to the control panel can exploit this by sending a crafted POST request to the reorder-sets endpoint to manipulate the order of Global Sets. The issue was resolved in version 4.18.1 by adding a 'requireAdmin()' check to the affected controller action.
