Technical details
Missing authorization controls in the /sys/sysDepartRole/exportXls endpoint allow authenticated users without appropriate permissions to invoke the underlying service.list() method through request parameters, bypassing tenant isolation and role-based access controls. The vulnerability affects the base JeecgController export handler which constructs database queries directly from request parameters and does not validate caller permissions. An attacker with any valid authentication credential can call the endpoint to exfiltrate sensitive authorization and organizational data.
