This high-severity CVE scores 8.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 66% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
