FeatherPanel versions before 1.3.7.10 fail to validate permissions in the SubuserController updateSubuser handler, allowing authenticated subusers to modify their own permission records. A subuser with minimal permissions can send a crafted request to grant themselves full server control, enabling unauthorized access to sensitive data, backups, and server configuration.
