{"schemaVersion":3,"id":"CVE-2026-24013","aliases":["PYSEC-2026-2080"],"status":"published","duplicateOf":null,"title":null,"description":"Authentication Bypass by Spoofing vulnerability in Apache IoTDB.\nCertain Thrift RPC query handlers lack strict validation of the sessionId\nparameter. An attacker can construct requests with a forged sessionId and,\nwithout performing openSession authentication, receive valid query results.\nThis allows authentication bypass and unauthorized reading of time-series\ndata.\n\n\nThis issue affects Apache IoTDB: from 1.3.3 before 2.0.8.\n\nUsers are recommended to upgrade to version 2.0.8, which fixes the issue.","dates":{"published":"2026-07-06T08:38:54.778Z","modified":"2026-07-06T20:37:57.934Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.1,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":9.1,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
