Description

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.

Affected products

• AWS Cloud Development Kit library: before 2.245.0 — fixed in 2.245.0

How to fix
