Description
Grav Flex-Objects before version 1.4.3 contains a broken access control vulnerability in the admin-next REST API that allows authenticated users with only api.access permission to perform unauthorized CRUD operations on permission-less directories. Attackers with api.access credentials can create, read, update, delete, and export objects from any directory lacking an explicit permissions configuration, bypassing intended authorization controls.
