EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 72% 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.474, PostgreSQL healthcheck command generation used attacker-controlled database settings (postgres_user and postgres_db) in shell-form commands, allowing an authenticated user to inject commands executed in the database container. This issue is fixed in version 4.0.0-beta.474.
