Apache · Apache Iotdb · CVE-2026-59229
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.
