{"schemaVersion":3,"id":"CVE-2026-23985","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A Regular Expression Denial of Service (ReDoS) vulnerability exists in Apache Superset versions 1.5.0 through 5.0.0. The vulnerability is located in the sql_parse.py component, specifically within the SQL_REGEX used for parsing SQL statements in the sqlparse library integration.\nThe affected regular expression contains overlapping disjunctions that share a common outer quantifier. An authenticated attacker can exploit this by sending a maliciously crafted input string (specifically a long sequence of backslashes or similar characters) to endpoints that process SQL queries\n\nThis issue affects Apache Superset: before 6.0.0.\n\nUsers are recommended to upgrade to version 6.0.0, which fixes the issue.\n\nWorkarounds:\n● WAF Rules: Implement Web Application Firewall (WAF) rules to detect and block\nrequests containing excessively long sequences of backslashes or suspicious repeated\npatterns in the queries.extras.where parameter.\n● Rate Limiting: Ensure strict rate limiting is applied to the /api/v1/chart/data endpoint to\nreduce the impact of potential attacks.","dates":{"published":"2026-07-30T16:09:24.026Z","modified":"2026-07-30T19:16:46.521Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":5.3,"severity":"medium","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":5.3,"severity":"medium","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00653,"percentile":0.50326,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0.24000000000000002,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.00413},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00653,"percentile":0.50326}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00413,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-05T00:00:00.
