The Legacy Pipe receiver protocol (handshake / sendPipeData) uses a hardcoded SUPER_USER (root) identity when executing data loading and deletion operations. A user with only SYSTEM-level privileges (such as USE_PIPE or MAINTAIN) who does NOT have WRITE_DATA or DELETE_DATA permissions on target databases can send specially crafted PipeData messages through the Legacy Pipe API, resulting in data loading/deletion operations executed as root — effectively bypassing IoTDB's permission model entirely. This issue affects Apache IoTDB: from 2.0.0 before 2.0.11. Users are recommended to upgrade to version 2.0.11, which fixes the issue.
