{"id":"CVE-2026-24012","summary":"Apache IoTDB: Denial of Service via Resource Exhaustion in Aggregation Query","details":"Uncontrolled Resource Consumption vulnerability in Apache IoTDB. \n\nSome interface fails to impose reasonable\nlimits on the time span and aggregation interval of the query. An attacker\ncan construct a request with extreme parameters (e.g., a very large time\nrange combined with a minimal interval). This forces the DataNode to build\nan enormous result set in memory, which exhausts the Java heap and causes\nthe DataNode process to crash.\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.","aliases":["PYSEC-2026-2079"],"modified":"2026-07-09T04:00:44.815610286Z","published":"2026-07-06T08:38:25.308Z","database_specific":{"unresolved_ranges":[{"extracted_events":[{"introduced":"1.3.3"},{"fixed":"2.0.8"}],"source":"AFFECTED_FIELD"},{"extracted_events":[{"introduced":"1.3.3"},{"fixed":"2.0.8"}],"source":"DESCRIPTION"}],"cwe_ids":["CWE-400"],"cna_assigner":"apache","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24012.json"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/07/06/10"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24012.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/0g5th1t2vj6j8hm5t9w3xh9n6f6ht9z8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24012"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/iotdb","events":[{"introduced":"ad95a7ee57990f7ce5d1503643a3b20936da51e7"},{"fixed":"b88b5dc62ffb0329fdc4dfd479fc46e9cf416a56"}],"database_specific":{"extracted_events":[{"introduced":"1.3.3"},{"fixed":"2.0.8"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:apache:iotdb:*:*:*:*:*:*:*:*"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-24012.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
