AI-suggested
Upgrade aws-cdk-lib to version 2.260.0 or later, which contains the official fix for this vulnerability. As a workaround, ensure that all modules and their version strings in the package.json file come from trusted sources to prevent injection of malicious content. Alternatively, use local bundling instead of Docker-based bundling to avoid the affected code path. The recommended remediation is to upgrade to the fixed version.
Description
Bulletin ID: 2026-050-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 07/01/2026 12:15 PM PDT Description: AWS CDK (aws-cdk-lib) is an open-source framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. We identified CVE-2026-13760, an OS command injection issue in the NodejsFunction Docker bundling pipeline in aws-cdk-lib before 2.260.0 that could allow an actor who controls dependency version strings in a project's package.json file to execute arbitrary commands on the host running the CDK toolchain via injected shell metacharacters in the OsCommand helper. This issue requires the actor to control the content of a package.json dependency version string that is processed during Docker-based bundling with nodeModules specified. Impacted versions: < 2.260.0 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
