CVE-2026-24013

criticalCVSS 9.1covered by 1 sourcefirst seen 2026-07-06

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.
