This reminds me of a job I had 15+ years ago where we did code reviews by emailing files to one another with our changes. It worked like this with the first part of the file being a script and the end of the file being a base64 encoded zip of the changed files. We had tooling that would pack them, but unpacking was done by execution. What could possibly go wrong with emailing executable scripts?
