Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, the executeInDocker() helper wraps commands in bash -c '{$command}' without escaping single quotes. User-controlled docker_compose_custom_build_command and docker_compose_custom_start_command fields are interpolated directly, allowing a single quote to break out of the bash -c argument and execute commands on the managed server host (outside the intended Docker container context). This vulnerability is fixed in 4.0.0-beta.464.
