CVE-2026-115418
Description
A flaw was found in @aws-cdk/aws-redshift-alpha. A SQL injection vulnerability in the database-query custom resource handlers allows an attacker capable of modifying construct property values to execute arbitrary SQL statements with superuser privileges on the Amazon Redshift cluster. By supplying crafted usernames, comments, or passwords, an attacker can achieve privilege escalation and unauthorized access to database resources.
Statement
This vulnerability is rated as Important because manipulating construct parameters enables complete administrative compromise of the underlying data warehouse cluster, despite requiring control over infrastructure definitions. Red Hat products do not distribute or support the AWS Cloud Development Kit redshift module, leaving supported platforms and default installations unaffected.
Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability
Technical Impact: Execute Unauthorized Code or Commands
Adversaries could execute system commands, typically by changing the SQL statement to redirect output to a file that can then be executed.
Confidentiality
Technical Impact: Read Application Data
Since SQL databases generally hold sensitive data, loss of confidentiality is a frequent problem with SQL injection vulnerabilities.
Authentication
Technical Impact: Gain Privileges or Assume Identity; Bypass Protection Mechanism
If poor SQL commands are used to check user names and passwords or perform other kinds of authentication, it may be possible to connect to the product as another user with no previous knowledge of the password.
Access Control
Technical Impact: Bypass Protection Mechanism
If authorization information is held in a SQL database, it may be possible to change this information through the successful exploitation of a SQL injection vulnerability.
Integrity
Technical Impact: Modify Application Data
Just as it may be possible to read sensitive information, it is also possible to modify or even delete this information with a SQL injection attack.
