CVE-2026-115418 - SQL injection in the database-query custom resource handlers in Amazon Web Services (AWS)
Bulletin ID: 2026-151-AWS
Scope: AWS
Content Type: Important (requires attention)
Publication Date: 10/26/2026 09:30 AM PDT
Description:
The AWS Cloud Development Kit (CDK) @aws-cdk/aws-redshift-alpha module provides experimental constructs that manage Amazon Redshift users, tables and privileges. We identified CVE-2026-115418, an issue where crafted user names, comments or passwords set in these constructs could change the SQL that runs with Amazon Redshift superuser privileges at deployment, including granting access to all cluster users. Exploiting the issue requires the ability to influence the CDK application's construct property values.
Impacted versions: <2.274.0-alpha.0
Resolution:
This issue has been addressed in @aws-cdk/aws-redshift-alpha version 2.274.0. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes. After upgrading, review existing table grants to PUBLIC.
Workarounds:
Use only trusted, developer-authored values for user names, comments and passwords in these constructs, and review existing table grants to PUBLIC.
