CVE-2026-24012 Apache Software Foundation CVE debrief

CVE-2026-24012 is an Uncontrolled Resource Consumption vulnerability in Apache IoTDB. The issue arises from certain interfaces failing to impose reasonable limits on query time spans and aggregation intervals. An attacker can construct a request with extreme parameters, such as a very large time range combined with a minimal interval, forcing the DataNode to build an enormous result set in memory. This exhausts the Java heap and causes the DataNode process to crash. The vulnerability affects Apache IoTDB versions from 1.3.3 before 2.0.8. Users are recommended to upgrade to version 2.0.8, which fixes the issue.

Who should care

Users of Apache IoTDB, particularly those who have not upgraded to version 2.0.8, should be aware of this vulnerability. The vulnerability has a CVSS score of 7.5 and is classified as HIGH severity. It allows for potential denial-of-service attacks by causing the DataNode process to crash.

Technical summary

The vulnerability is caused by the lack of reasonable limits on query time spans and aggregation intervals in certain interfaces of Apache IoTDB. This allows an attacker to construct a malicious request that can lead to a denial-of-service condition. The issue affects versions from 1.3.3 before 2.0.8. The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H. Users of Apache IoTDB should be aware of the potential for denial-of-service attacks due to the uncontrolled resource consumption vulnerability. The vulnerability has a CVSS score of 7.5 and is classified as HIGH severity.

Defensive priority

High priority should be given to upgrading Apache IoTDB to version 2.0.8 or later. In the meantime, users can consider implementing compensating controls such as monitoring for unusual query patterns and limiting the size of result sets.

Recommended defensive actions

  • Upgrade Apache IoTDB to version 2.0.8 or later
  • Monitor for unusual query patterns
  • Limit the size of result sets
  • Implement additional logging and monitoring to detect potential attacks
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
