Arbitrary file upload in Apache Iotdb
CVE-2026-24014
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.
