CVE-2026-24013: Apache Iotdb

Critical severity, CVSS 9.1. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Apache Iotdb: from 1.3.3, before 2.0.8 (fixed in 2.0.8)
