# CVE-2026-115418: SQL injection in the database-query custom resource handlers in Amazon Web Services (AWS) Cloud Development Kit (CDK) @aws-cdk/aws-redshift-alpha

Status: published. Published: 2026-10-26. Updated: 2026-11-02.

SQL injection in the database-query custom resource handlers in the Amazon Web Services (AWS) Cloud Development Kit (CDK) @aws-cdk/aws-redshift-alpha module before 2.274.0-alpha.0 could allow a third party who can influence construct property values to run SQL statements with Amazon Redshift superuser privileges, including granting access to all cluster users. The statements are reachable through crafted user names, comments, or passwords.



To remediate this issue, users should upgrade to version 2.274.0-alpha.0 or later and review existing table grants to PUBLIC.
