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

Severity: high (CVSS 8.8 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.3% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2026-10-21 · updated 2026-10-30
Weakness: CWE-798

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.

Affected products

Apache Software Foundation Apache IoTDB: from 2.0.0 before 2.0.11 — fixed in 2.0.11

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache IoTDB 2.0.11. Check the vendor advisory for mitigations.
