CVE-2026-24012 iotdb vulnerability
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.
Quick answer
apache iotdb should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.
Who is affected
Affected versions
- Review vendor advisory for affected versions.
Fixed versions
- Apply the latest vendor-supported patched version.
How to fix it
CVE-2026-24012 affects Apache IoTDB Apache IoTDB. Upgrade IoTDB to 2.0.8 and restrict DataNode/Thrift/internal RPC exposure while validating authentication, trigger upload, and query-limit behavior. Affected ranges in the local record are 1.3.3 through before 2.0.8.
- Inventory every Apache IoTDB DataNode, ConfigNode, client, container image, and deployment manifest in production and staging.
- Confirm whether DataNode internal RPC, Thrift query endpoints, trigger upload functions, or time-series aggregation APIs are reachable from untrusted networks.
- Upgrade Apache IoTDB to 2.0.8, or a later vendor-supported release, across all cluster nodes before re-enabling broad access.
- Block untrusted access to internal RPC and administrative ports with firewall, security group, Kubernetes NetworkPolicy, or service mesh rules.
- Review trigger JAR upload paths, session validation, and query time-span limits; disable risky functions until the patched version is active everywhere.
- Rebuild containers and redeploy the cluster in a rolling plan that preserves quorum and validates schema, trigger, and query compatibility.
- Inspect logs and audit data for forged sessions, path traversal strings, unexpected trigger files, heap exhaustion, or large aggregation queries during the exposure window.

Verify the fix
- Confirm each IoTDB node reports 2.0.8 or a later fixed release after deployment.
- Verify untrusted networks cannot reach DataNode internal RPC, Thrift query handlers, or trigger upload endpoints.
- Run negative tests for forged sessionId requests, path traversal in trigger names, and excessive aggregation intervals, and confirm patched behavior.
- Open the generated Fixnx page and confirm the canonical URL ends with iotdb-cve-2026-24012.
- Re-run sitemap validation and confirm iotdb-cve-2026-24012 appears once in sitemap.xml with the full CVE-2026-24012 suffix.
