Overview
aws-cdk-lib is a Version 2 of the AWS Cloud Development Kit library
Affected versions of this package are vulnerable to Symlink Attack in the asset bundling output handling, which accepts a symbolic link that the Docker build placed in the output directory even though no such link was supplied as bundling input. An attacker who controls the Dockerfile, or code running inside the bundling container, can place a symbolic link into the produced asset that points outside the supplied inputs. This requires asset bundling with a Docker file.
