Uncontrolled Resource Consumption in Apache IoTDB

Publication date: 2026-07-06

Last updated on: 2026-07-06

Assigner: Apache Software Foundation

Description
Uncontrolled Resource Consumption vulnerability in Apache IoTDB.  Some interface fails to impose reasonable limits on the time span and aggregation interval of the query. An attacker can construct a request with extreme parameters (e.g., a very large time range combined with a minimal interval). This forces the DataNode to build an enormous result set in memory, which exhausts the Java heap and causes the DataNode process to crash. 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.

Executive Summary

This vulnerability is an Uncontrolled Resource Consumption issue in Apache IoTDB. Some interfaces do not properly limit the time span and aggregation interval parameters of queries. An attacker can exploit this by sending a request with extreme parameters, such as a very large time range combined with a minimal interval. This causes the DataNode to generate an enormous result set in memory, exhausting the Java heap and causing the DataNode process to crash.

Impact Analysis

The impact of this vulnerability is that an attacker can cause the Apache IoTDB DataNode process to crash by exhausting its memory resources. This leads to denial of service, making the database unavailable and potentially disrupting any services or applications relying on it.

Mitigation Strategies

To mitigate this vulnerability, users are recommended to upgrade Apache IoTDB to version 2.0.8, which contains the fix for this uncontrolled resource consumption issue.
