Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Coolify versions prior to 4.0.0-beta.469 contain a command injection vulnerability in the generate_healthcheck_commands() function within ApplicationDeploymentJob.php. Authenticated users can manipulate health_check_host, health_check_method, and health_check_path parameters to inject arbitrary shell commands that execute within deployment containers.

MitigationUpgrade Coolify to version 4.0.0-beta.469 or later. Until then, restrict access to health check configuration to trusted personnel only and monitor for suspicious command patterns in container logs.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Coolify version
    Run 'coolify --version' from the Coolify CLI or check the version displayed in the Coolify web UI dashboard
    Affected if Version is lower than 4.0.0-beta.469 (e.g., 4.0.0-beta.450, 3.x.x releases)
  2. Verify health check configuration access
    Navigate to application deployment settings in Coolify UI and review health_check_host, health_check_method, and health_check_path parameters for any custom or user-supplied values
    Affected if Health check parameters are configurable by users and the Coolify version is below 4.0.0-beta.469
  3. Inspect deployment container logs
    Examine logs from recent application deployments for unusual shell command patterns, unexpected payloads, or suspicious strings in health check related entries
    Affected if Logs contain commands or arguments that were not explicitly defined by administrators, indicating potential injection attempts
  4. Review user permissions on deployment workflows
    Check which user roles have access to modify application health check configuration in the Coolify administration panel
    Affected if Non-admin or untrusted users have permission to configure health check parameters and the Coolify version is vulnerable

You are affected if your Coolify version is prior to 4.0.0-beta.469 and users with deployment access can configure health check parameters.

Interim mitigation

Upgrade Coolify to version 4.0.0-beta.469 or later. Until then, restrict access to health check configuration to trusted personnel only and monitor for suspicious command patterns in container logs.

Recommended fix High confidence

4.0.0-beta.469

  1. Upgrade Coolify to version 4.0.0-beta.469 or later to resolve the command injection vulnerability in the generate_healthcheck_commands() function
