CVE-2026-42201: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in coollabsio coolify
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.

Technical Summary
CVE-2026-42201 describes an OS command injection vulnerability in Coolify, an open-source server and application management tool. Before version 4.0.0-beta.474, database credential fields such as redis_password, keydb_password, dragonfly_password, clickhouse_admin_user, clickhouse_admin_password, postgres_user, and mysql_user are only validated as strings at the API layer without any shell escaping. These values are then directly interpolated into Docker Compose YAML command strings, which can lead to improper neutralization of special elements used in OS commands (CWE-78). This issue is resolved in version 4.0.0-beta.474.
Potential Impact
An attacker with the ability to supply database credential fields could exploit this vulnerability to inject OS commands due to improper input sanitization. The impact is limited to low confidentiality and integrity loss, with no availability impact reported. The CVSS vector indicates the attack requires network access, high attack complexity, and privileges, with no user interaction needed.
Mitigation Recommendations
Upgrade to Coolify version 4.0.0-beta.474 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are documented. Patch status is not explicitly confirmed beyond the fix in 4.0.0-beta.474, so users should verify vendor advisories for updates.
