Summary

A ReDoS vulnerability in Apache Superset, located in the sql_parse.py component, allows an authenticated attacker to cause significant server load by sending a crafted SQL query with a long string of characters. This can lead to denial of service.

Risk Assessment

The risk is a potential DoS attack that could render the Superset service unavailable, impacting business analytics availability.

Recommendation

Upgrade Apache Superset to version 6.0.0. As a temporary workaround, implement WAF rules to block long backslash sequences and apply rate limiting to the /api/v1/chart/data endpoint.

Other vulnerabilities in Apache Superset

CVE-2026-23981Medium
An improper authorization vulnerability in Apache Superset allows an authenticated user with chart update permissions to modify dashboards they do not own. This occurs because the validation in UpdateChartCommand does not check write permissions for target dashboards.

Original NVD description (English 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.
