OS command injection in the `NodejsFunction` local bundling pipeline in `aws-cdk-lib` before 2.245.0 (2.246.0 on Windows) might allow a threat 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.\n\n### Impact\nDuring local Lambda bundling, `NodejsFunction` assembled an esbuild command string from the bundling properties `externalModules`, `define`, `loader`, `inject`, and `esbuildArgs` and executed it via a shell (`bash -c` on Linux/macOS, `cmd /c` on Windows) through `spawnSync`. The property values were interpolated without escaping or validation, so values containing shell metacharacters could execute arbitrary commands with the privileges of the user running `cdk synth`, `cdk deploy`, or `cdk diff`.
