An unauthenticated\nattacker can send a stream of repeated E-language prefixes that drives the\nrecursion arbitrarily deep, exhausting the receiver thread's JVM stack and\nraising StackOverflowError.\n\n\nThis issue affects Apache IoTDB: from 1.0.0 before 2.0.10.\n\nUsers are recommended to upgrade to version 2.0.10, which fixes the issue.","published":"2026-07-10T08:16:22.000Z","lastModified":"2026-10-25T15:10:00.000Z","status":"Deferred","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-400","CWE-674"],"affected":[],"epss":{"score":0.00488,"percentile":0.41795,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.49%).
