CVE-2026-108888 · Severity: medium · CVSS 4.3 · Published 2026-10-11

JeecgBoot is a Java-based enterprise application development framework. The SysDepartRoleController exportXls handler fails to properly restrict access to exported data, allowing any authenticated user to download sensitive department role and authorization information that should only be accessible to administrators. This grants low-privileged users access to role names, codes, descriptions, and user account information without proper authorization checks.

## 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.
