aws-cdk-lib: OS Command Injection in NodejsFunction Docker Bundling
GitHub lists this reviewed advisory for aws-cdk-lib. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

aws-cdk-lib
source listed< 2.260.0
### Summary AWS CDK (aws-cdk-lib) is an open-source framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. OS command injection issue in the NodejsFunction Docker bundling pipeline in aws-cdk-lib before 2.260.0 that might 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. ### Impact During Docker-based Lambda bundling, when the nodeModules option is specified, NodejsFunction assembled a shell command string, including file-operation commands generated by an internal OsCommand helper, from the version strings of the modules listed in nodeModules, and executed it via a shell (bash -c) inside the bundling container. These version strings were interpolated without shell escaping, so values containing shell metacharacters could execute arbitrary commands inside the bundling container - which has read/write bind
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. FIRST EPSS
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
