CVE-2026-59229: Apache IoTDB: Legacy Pipe Privilege Escalation

[Haonan Hou <haonan () apache org>]

Severity: important 

Affected versions:

- Apache IoTDB 2.0.0 before 2.0.11

Description:

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.
