CVE-2026-24013

Authentication Bypass by Spoofing vulnerability in Apache IoTDB.
Certain Thrift RPC query handlers lack strict validation of the sessionId
parameter. An attacker can construct requests with a forged sessionId and,
without performing openSession authentication, receive valid query results.
This allows authentication bypass and unauthorized reading of time-series
data.


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.
