DescriptionCVE.org

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.

AnalysisAI

OS command injection in AWS aws-cdk-lib lets an actor who controls a dependency version string in a project's package.json run arbitrary commands on the host executing the CDK toolchain. The flaw lives in the OsCommand helper of the NodejsFunction Docker bundling pipeline, which passes unsanitized version strings into a shell during nodeModules installation. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; AWS has released a fixed version (v2.260.0).

Technical ContextAI

AWS CDK (Cloud Development Kit) is an infrastructure-as-code framework; the affected aws-cdk-lib construct library includes the NodejsFunction construct, which can bundle Lambda function dependencies inside a Docker container. During Docker-based bundling with nodeModules specified, the toolchain builds shell commands to install the named dependencies at their declared versions. The internal OsCommand helper composes these commands but fails to neutralize shell metacharacters (CWE-78, OS Command Injection) present in the dependency version strings drawn from package.json, so attacker-controlled version text is interpreted by the shell rather than treated as literal data. The affected component is identified by CPE cpe:2.3:a:aws:aws_cdk:*:*:*:*:*:*:*:* across all platforms.

RemediationAI

Vendor-released patch: v2.260.0 - upgrade aws-cdk-lib to 2.260.0 or later (release notes at https://github.com/aws/aws-cdk/releases/tag/v2.260.0; advisories at https://aws.amazon.com/security/security-bulletins/2026-050-aws/ and https://github.com/aws/aws-cdk/security/advisories/GHSA-vcrf-j523-4mrf). Until you can upgrade, reduce exposure by avoiding Docker-based bundling with nodeModules for NodejsFunction (for example by using local esbuild bundling or pre-built assets), which removes the vulnerable OsCommand path but changes how dependencies are packaged; additionally validate or pin dependency version strings in package.json and treat any package.json originating from untrusted contributors or third-party dependencies as untrusted input, and run CDK synth/bundling in isolated, least-privilege CI runners so a successful injection cannot reach long-lived credentials.
