{"id":"BIT-superset-2026-23985","summary":"Apache Superset: Regular Expression Denial of Service (ReDoS) in SQL Parser","details":"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.","aliases":["CVE-2026-23985"],"modified":"2026-09-08T08:48:10.808460474Z","published":"2026-08-17T05:55:44.269Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:apache:superset:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/07/30/7"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/fdy7tx7glv90ypd7qnm1g1pt7nn336qx"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23985"}],"affected":[{"package":{"name":"superset","ecosystem":"Bitnami","purl":"pkg:bitnami/superset"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"6.0.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/superset/BIT-superset-2026-23985.json"},"severity":[{"type":"CVSS_V4","score":"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"}]}],"schema_version":"1.9.0"}
