Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.469, Coolify's app/Jobs/ApplicationDeploymentJob.php generate_healthcheck_commands() function directly interpolated the health_check_host, health_check_method, and health_check_path parameters into shell commands without proper sanitization, allowing authenticated users to execute arbitrary commands inside deployment containers. This issue is fixed in version 4.0.0-beta.469.
