CVE-2026-42201 – Coolify: OS Command Injection via Database Credential Fields in Docker Compose Service Commands

CVE ID :CVE-2026-42201

Published : July 7, 2026, 5:16 a.m. | 31 minutes ago

Description :Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.474, database credential fields (redis_password, keydb_password, dragonfly_password, clickhouse_admin_user, clickhouse_admin_password, postgres_user, mysql_user) are validated only as ‘string’ at the API layer, with zero shell-safety checks. These values are then interpolated directly into Docker Compose YAML command: strings without any escaping. This issue is fixed in version 4.0.0-beta.474.

Severity: 3.3 | LOW
