CVE-2026-13760

OS Command Injection in aws-cdk-lib Docker Bundling

State: Published
Severity: 7.0 High
Published: Jul 1, 2026
Updated: Jul 1, 2026
Reserved: Jun 29, 2026

Description

OS command injection in the NodejsFunction Docker bundling pipeline (OsCommand helper) in AWS aws-cdk-lib on all platforms might allow a 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.

To remediate this issue, users should upgrade to v2.260.0.
