CVE-2026-24013Network attack vector

Unauthenticated data access via forged session identifier

Published Jul 6, 2026 · Updated Jul 6, 2026

Authentication bypass in Apache IoTDB 1.3.3 through 2.0.7 allows remote attackers to read time-series data through Thrift RPC. Certain Thrift RPC query handlers accept a caller-supplied sessionId without strictly validating that it belongs to an authenticated openSession. A remote attacker needs network access to the Thrift RPC service and can forge the identifier to receive query results without credentials; the published impact is unauthorized reading of stored time-series data.
