Threats affecting pkg:npm/aws-cdk-lib

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.

CVE-2026-107608 is a vulnerability in aws-cdk-lib where the asset bundling process using Docker files could improperly include symlinked files or directories in the output without those symlinks being part of the input. This affects all versions prior to 2.267.0. The issue arises when bundling assets with Docker files, potentially causing unexpected files to be included in the deployment package.

OS command injection in the NodejsFunction local bundling pipeline in aws-cdk-lib before 2.245.0 (2.246.0 on Windows) might allow an actor who controls the value of one or more bundling properties (externalModules, define, loader, inject, or esbuildArgs) to execute arbitrary commands on the host running the CDK toolchain via injected shell metacharacters. This issue requires the threat actor to control the value of one or more of the affected bundling properties in the CDK application. To remediate this issue, users should upgrade to aws-cdk-lib 2.245.0 (2.246.0 on Windows) or later.
