CVE-2026-2860Public exploitNetwork attack vector

Employee data exposure via missing endpoint authorization

Published Feb 21, 2026 · Updated Feb 21, 2026

Improper authorization in MegaGao production_ssm allows remote authenticated users to read employee identity data via the employee list endpoint. EmployeeController returns ID-card records because /employee/list lacks Shiro authorization annotations. A low-privileged authenticated session can enumerate employee identity data; no code execution or service interruption is shown.
