JHipster before v.8.9.0 allows privilege escalation via a modified authorities parameter. Upon registering in the JHipster portal and logging in as a standard user, the authorities parameter in the response from the api/account endpoint contains the value ROLE_USER. By manipulating the authorities parameter and changing its value to ROLE_ADMIN, the privilege is successfully escalated to an Admin level. This allowed the access to all admin-related functionalities in the application.
