CVE-2026-24014: Apache IoTDB: Path Traversal in DataNode Internal RPC Trigger JAR Upload Allows Arbitrary File Write

[Haonan Hou <haonan () apache org>]

Severity: important 

Affected versions:

- Apache IoTDB 1.3.3 before 2.0.8

Description:

Apache IoTDB DataNode’s internal RPC interface for creating Trigger instances uses the uploaded Trigger JAR name to 
build a file path without sufficient validation. If the internal DataNode RPC port is exposed to an untrusted network, 
an attacker may use path traversal sequences in the JAR name to write files outside the intended Trigger installation 
directory. This could allow arbitrary file write with the permissions of the IoTDB process.

This issue affects Apache IoTDB: from 1.3.3 before 2.0.8.

Users are recommended to upgrade to version 2.0.8, which fixes the issue.
