Vulnerability in Apache Superset (CVE-2026-23985)
Summary
Vulnerability in Apache Superset (CVE-2026-23985). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
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.
The 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
This issue affects Apache Superset: before 6.0.0.
Users are recommended to upgrade to version 6.0.0, which fixes the issue.
Workarounds:
● WAF Rules: Implement Web Application Firewall (WAF) rules to detect and block
requests containing excessively long sequences of backslashes or suspicious repeated
patterns in the queries.extras.where parameter.
● Rate Limiting: Ensure strict rate limiting is applied to the /api/v1/chart/data endpoint to
reduce the impact of potential attacks.
