CVE-2026-40008 Details
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. This issue affects Apache IoTDB: from 1.0.0 before 2.0.10. Users are recommended to upgrade to version 2.0.10, which fixes the issue.
A vulnerability allowing unsafe reflection has been identified in Apache IoTDB versions 1.0.0 prior to 2.0.10. This issue arises because the pipe processor can read a fully qualified Java class name and instantiate it using Class.forName().newInstance() without any validation or allowlisting. As a result, this vulnerability could be exploited to instantiate arbitrary classes, potentially leading to further security issues.
Users are advised to upgrade to Apache IoTDB version 2.0.10 or later, which addresses this vulnerability.
