CVE-2026-44630Apache IoTDB: RPC service denial of service via unchecked Thrift string length
High 7.5
In plain English
A high-severity uncontrolled resource consumption in Apache IoTDB from Apache Software Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.6% (higher than 48% of all known vulnerabilities).
Official description
Improper validation of length fields in the Apache IoTDB RPC service may allow a remote unauthenticated attacker to cause a denial of service. By sending a crafted malformed Thrift frame, an attacker can cause IoTDB to allocate an excessive amount of memory and crash with an OutOfMemoryError. This issue affects Apache IoTDB: before 1.3.8, from 2.0.0 before 2.0.9. Users are recommended to upgrade to version 2.0.10, which fixes the issue.
