CVE-2026-42153Public exploitNetwork attack vector

Authenticated container-root execution via shell-form healthcheck

Published Jul 6, 2026 · Updated Jul 6, 2026

OS command injection in Coolify before 4.0.0-beta.474 allows remote authenticated users to execute commands as root in PostgreSQL containers. StartPostgresql.php interpolates postgres_user and postgres_db into a CMD-SHELL healthcheck that /bin/sh parses without escaping. Any member account can create and start a PostgreSQL database, exposing its data and credentials to commands running inside that container.
