Just had this one in the building dependancies

Start by tracing the angular-shepherd > shepherd.js > deepmerge-ts dependency path in the project manifests and lockfile. Confirm that the resolved deepmerge-ts version is at least 8.0.0, then run the existing build or test checks; done means the vulnerable dependency path is no longer present.
