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.","published":"2026-07-30T16:17:11.000Z","lastModified":"2026-10-23T22:10:00.000Z","status":"Analyzed","sourceIdentifier":"security@apache.org","cvss":{"version":"4.0","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/M"},"cwe":["CWE-1333"],"affected":["apache/superset"],"epss":{"score":0.00653,"percentile":0.50984,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.65%).
