Unauthenticated user-data disclosure via exposed API

Published Feb 14, 2022 · Updated Aug 4, 2024

Incorrect access control in zuiidea antd-admin 5.5.0 allows remote attackers to read user records through an exposed HTTP API. The /api/v1/users endpoint returns user IDs, names, ages, phone numbers, and addresses without requiring authentication. Network access to the deployed web interface is sufficient; published evidence shows disclosure only, not modification or interruption.
