CVE-2026-62845 clastix CVE debrief

Who should care

Users of Kamaji, the Hosted Control Plane Manager for Kubernetes, should be aware of this vulnerability and take steps to mitigate it. This includes inventory checks, applying patches, and implementing additional security measures. Operators, platform administrators, vulnerability management teams, and security teams should review the vulnerability details and assess their exposure. They should also verify the version of Kamaji in use and plan for upgrades or mitigations as necessary. Additionally, they should implement monitoring and detection measures to identify potential exploitation attempts. Compensating controls such as Web Application Firewalls may also be considered for exposed systems while remediation is scheduled and verified. It is also recommended to track exceptions, retest remediated assets, and close the item only after evidence is documented. This vulnerability may impact the security posture of Kubernetes environments using Kamaji, and proactive measures are essential to prevent potential attacks. Security teams should prioritize this vulnerability based on its CVSS score and the potential impact on their systems. They should also review the official advisory and CVE record to validate affected scope, severity, and vendor guidance. Finally, they should plan for vendor-supported updates or mitigations through normal change control where exposure is confirmed. This may involve coordinating with vendors, testing patches, and implementing changes to prevent exploitation. By taking these steps, organizations can reduce the risk associated with this vulnerability and protect their Kubernetes environments from potential attacks. The vulnerability highlights the importance of secure coding practices, thorough testing, and timely patching to prevent SQL injection attacks. It also underscores the need for robust security measures, such as monitoring and incident response planning, to detect and respond to potential security incidents. Overall, a proactive and multi-faceted approach is necessary to address this vulnerability and maintain the security and integrity of Kubernetes environments. To further enhance security, consider implementing additional防御

Technical summary

The PostgreSQL and MySQL datastore drivers in Kamaji build DDL statements by interpolating user-supplied DataStoreUsername/DataStoreSchema directly into SQL without proper escaping, leading to a SQL injection vulnerability. The etcd driver is not affected. The issue is fixed in version 26.7.4-edge. This vulnerability has a CVSS score of 4.7, indicating a medium severity level. The vulnerability highlights the importance of secure coding practices, thorough testing, and timely patching to prevent SQL injection attacks. It also underscores the need for robust security measures, such as monitoring and incident response planning, to detect and respond to potential security incidents.

Defensive priority

Medium priority given the CVSS score of 4.7 and the potential for SQL injection attacks.

Recommended defensive actions

• Inventory and verify the version of Kamaji in use to determine if it is vulnerable.
• Apply the patch to upgrade to version 26.7.4-edge or later.
• Implement additional monitoring to detect potential SQL injection attacks.
• Review and restrict access to the shared datastore.
• Consider compensating controls such as Web Application Firewalls.

Evidence notes

The CVE record indicates that Kamaji, the Hosted Control Plane Manager for Kubernetes, has a vulnerability in its PostgreSQL and MySQL datastore drivers. The vulnerability allows for SQL injection attacks due to improper escaping of user-supplied input. The etcd driver is not affected. The issue is fixed in version 26.7.4-edge. To verify, defenders should check the version of Kamaji in use, review the patch notes for 26.7.4-edge, and assess their exposure to the vulnerability.
