CVE-2026-23985 Apache CVE debrief

Who should care

Users of Apache Superset versions 1.5.0 through 5.0.0 should be aware of this vulnerability and take necessary actions to mitigate it. This includes upgrading to version 6.0.0 or later and implementing WAF rules to detect and block suspicious queries. Operators, platform administrators, vulnerability management teams, and security teams should review the CVE record and NVD details for specific guidance on affected deployments and mitigation strategies. Strict rate limiting on the /api/v1/chart/data endpoint is also recommended to reduce potential attack impact. Monitoring and detection capabilities should be reviewed to ensure they can identify potential exploitation attempts. Asset inventory and change management processes should be updated to prioritize affected systems for remediation. Rollback and change window planning should consider the potential for service disruption during updates. Source tracking and logging should be enhanced to detect similar vulnerabilities in the future. Compensating controls, such as additional monitoring or access restrictions, may be necessary for exposed systems while remediation is scheduled and verified. Exceptions and retesting of remediated assets should be tracked, and items should only be closed after evidence of successful remediation is documented. This vulnerability highlights the importance of robust input validation and regular security updates in software deployments. It also underscores the need for proactive vulnerability management and incident response planning to minimize potential impact. By taking these steps, organizations can enhance their security posture and reduce the risk associated with this and similar vulnerabilities. Regular review of security advisories and prompt application of patches are critical in maintaining a secure environment. Collaboration between development, operations, and security teams is essential in effectively managing and mitigating vulnerabilities like CVE-2026-23985. The vulnerability's medium severity emphasizes the need for prompt attention and mitigation efforts to prevent potential denial-of-service attacks. Overall, a comprehensive approach to vulnerability management,结合人

Technical summary

The vulnerability is caused by a ReDoS in the sql_parse.py component of Apache Superset. An authenticated attacker can exploit this by sending a maliciously crafted input string to endpoints that process SQL queries. The affected versions are Apache Superset 1.5.0 through 5.0.0. Users should be cautious with input strings that could trigger the ReDoS. The CVSS score of 5.3 indicates a medium severity.

Defensive priority

Medium priority due to the CVSS score of 5.3 and the potential for denial of service attacks.

Recommended defensive actions

• Upgrade to version 6.0.0 or later
• Implement WAF rules to detect and block suspicious queries
• Apply strict rate limiting to the /api/v1/chart/data endpoint
• Review and update asset inventory to prioritize affected systems for remediation
• Enhance monitoring and detection capabilities to identify potential exploitation attempts
• Implement compensating controls for exposed systems while remediation is scheduled and verified
• Track exceptions and retest remediated assets to ensure successful remediation

Evidence notes

The CVE record and NVD details provide information about the vulnerability, its impact, and affected versions. However, further analysis is limited by the available data. To verify, defenders should check the official CVE record and NVD details for CVE-2026-23985. The sql_parse.py component in Apache Superset versions 1.5.0 through 5.0.0 is affected, specifically within the SQL_REGEX used for parsing SQL statements in the sqlparse library integration. The vulnerability allows an authenticated attacker to exploit it by sending a maliciously crafted input string to endpoints that process SQL queries. Evidence limits suggest focusing on CVE and NVD for verified details.
