CVE-2026-40008: CWE-470 Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') in Apache Software Foundation Apache IoTDB
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.
AI Analysis
Technical Summary
CVE-2026-40008 is a critical vulnerability in Apache IoTDB where the pipe processor uses externally-controlled input to select and instantiate Java classes via Class.forName().newInstance() without validation or allowlisting. This unsafe reflection can allow attackers to execute arbitrary code by supplying malicious class names. The vulnerability affects Apache IoTDB versions from 1.0.0 before 2.0.10. The issue is fixed in version 2.0.10.
Potential Impact
Successful exploitation could lead to remote code execution with high confidentiality, integrity, and availability impact, as indicated by the CVSS score of 9.8. Attackers can instantiate arbitrary classes, potentially compromising the system running Apache IoTDB.
Mitigation Recommendations
Users should upgrade Apache IoTDB to version 2.0.10 or later, where this vulnerability is fixed. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the vendor advisory recommending the upgrade.
