Dokploy is a free, self-hostable Platform as a Service (PaaS). In 0.29.2 and earlier, Dokploy constructs shell commands using JavaScript template literals and executes them via child_process.exec() (which runs through /bin/sh -c). User-supplied branch names, repository URLs, and Docker credentials are interpolated directly into these commands without escaping. This requires an authenticated user with application create/edit privileges.
