Last updated on: 2026-07-10

Assigner: Apache Software Foundation

Description
Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability in Apache IoTDB. The pipe processor reads a fully qualified Java class name and instantiates it using Class.forName().newInstance() without any validation or allowlisting.

Executive Summary

This vulnerability is an Unsafe Reflection issue in Apache IoTDB where the pipe processor reads a fully qualified Java class name and instantiates it using Class.forName().newInstance() without any validation or allowlisting.

Because the input is externally controlled and not validated, an attacker can supply arbitrary class names, potentially causing the system to execute unintended or malicious code.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary code on the affected system by supplying malicious class names that get instantiated without validation.

Such unauthorized code execution can lead to system compromise, data breaches, or disruption of service.

Mitigation Strategies

Users are recommended to upgrade Apache IoTDB to version 2.0.10, which fixes the unsafe reflection vulnerability.
