Description

Grav Flex Objects Plugin allows you to build custom collections of objects. Prior to 1.4.3, the Grav Flex Objects Admin Next API requireFlexPermission() method in classes/Api/FlexApiController.php returns without denying access when a directory blueprint omits config.admin.permissions. An authenticated account with only api.access can use the index, show, create, update, delete, export, and media handlers for a permission-less directory even though the core admin.flex-object. authorization fallback would deny the same actions. This issue is fixed in version 1.4.3.
