## Overview

JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysTenantController listPackByTenantUserId handler that allows any authenticated user to query tenant product packs. Low-privileged attackers can supply arbitrary tenantId and userId parameters to enumerate any tenant's product pack configuration and reveal which users are tenant administrators.
