Values supplied through docker options, `--ttl-seconds`, and `-e` flowed into a Bash `eval` during build, deploy, and run, letting a low-privileged user execute arbitrary commands on the host as the dokku user. These arguments are now tokenized and passed through to the container verbatim, without shell expansion. A one-time migration repairs stored labels whose backticks were saved with a stray backslash so Traefik-style rules stay valid on the next deploy.
Emitting the restart policy as a `--restart` argument from a `docker-args-process-deploy` trigger exposed a latent gluing bug: proxy and builder triggers concatenated `$STDIN$output` with no separator, and the scheduler and builders appended `docker-args-process-*` output directly onto the older `docker-args-*` output, so adjacent arguments could merge into values like `--restart=on-failure:10--label`. A space is now inserted at both the trigger echo and the concatenation so arguments always stay separated.
