Technical details

The getTenantPackInfo endpoint in SysTenantController lacks authorization checks and directly returns sensitive administrator pack membership information based on caller-supplied tenantId and packCode parameters. An authenticated attacker can enumerate fixed pack codes (superAdmin, accountAdmin, appAdmin) across tenants to disclose administrator identity details including username, realname, phone, avatar, and department names without permission.
