CVE-2026-23980 is a SQL Injection vulnerability classified under CWE-89, found in Apache Superset versions prior to 6.0.0. Apache Superset is an open-source data visualization and business intelligence platform widely used for interactive data exploration. The vulnerability arises due to improper neutralization of special elements in SQL commands, specifically through the sqlExpression or where parameters. An authenticated user with read access can exploit this flaw to inject malicious SQL code, leveraging error-based SQL injection techniques to extract sensitive information from the underlying database. The vulnerability does not require elevated privileges beyond read access, nor does it require user interaction, making it easier to exploit in environments where users have read permissions. The CVSS 4.0 base score is 5.3 (medium), reflecting network attack vector, low attack complexity, no privileges required beyond read access, and no user interaction needed. The scope is limited to confidentiality impact, with no direct impact on integrity or availability. Apache Superset 6.0.0 includes fixes that properly sanitize inputs to prevent injection attacks. No public exploits have been reported yet, but the presence of this vulnerability in a widely deployed analytics platform poses a significant risk if left unpatched.

The primary impact of CVE-2026-23980 is unauthorized disclosure of sensitive data due to SQL Injection. Attackers with read access can exploit this vulnerability to extract confidential information from backend databases, potentially exposing business intelligence data, user information, or proprietary analytics. This can lead to data breaches, compliance violations, and loss of trust. While the vulnerability does not directly affect data integrity or system availability, the exposure of sensitive data can facilitate further attacks or insider threats. Organizations relying on Apache Superset for critical analytics and reporting are at risk, especially if deployed in environments with sensitive or regulated data. The ease of exploitation without elevated privileges increases the threat level in multi-tenant or shared environments. Additionally, attackers could use the information gained to escalate privileges or pivot within the network, amplifying the overall impact.

To mitigate CVE-2026-23980, organizations should immediately upgrade Apache Superset to version 6.0.0 or later, where the vulnerability is patched. Until the upgrade can be performed, restrict read access to trusted users only and monitor database query logs for unusual or suspicious SQL patterns indicative of injection attempts. Implement strict input validation and sanitization on any custom extensions or integrations that interact with the sqlExpression or where parameters. Employ web application firewalls (WAFs) with SQL injection detection rules tailored to Superset’s query patterns. Conduct regular security audits and penetration testing focused on injection vulnerabilities in analytics platforms. Additionally, enforce the principle of least privilege by limiting database user permissions associated with Superset to minimize potential data exposure. Maintain up-to-date backups and ensure incident response plans include scenarios involving data leakage through injection attacks.
