Description

This came up during the security review. pack build <trusted-builder> --buildpack <untrusted-buildpack> would allow a malicious buildpack to run in the same container as registry credentials and/or the docker socket.

Proposed solution

If any buildpacks are added (via --buildpack, --extension or project.toml) we should use the untrusted (5 phases) flow. We should probably make an exception for inline buildpacks as these are added directly by the developer.

Describe alternatives you've considered
