CVE-2026-42153: 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, 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.
AI Analysis
Technical Summary
CVE-2026-42153 is an OS command injection vulnerability (CWE-78) affecting coollabsio's Coolify before version 4.0.0-beta.474. The vulnerability arises from the use of attacker-controlled parameters (postgres_user and postgres_db) in shell-form commands for PostgreSQL healthchecks, enabling an authenticated user to inject and execute arbitrary commands inside the database container. This can lead to full compromise of confidentiality, integrity, and availability of the affected system. The vulnerability has a CVSS 3.1 score of 8.8, indicating high severity. The issue is resolved in version 4.0.0-beta.474.
Potential Impact
Successful exploitation allows an authenticated user to execute arbitrary OS commands within the database container, potentially leading to full system compromise including data theft, modification, or service disruption.
Mitigation Recommendations
Upgrade to Coolify version 4.0.0-beta.474 or later, where this vulnerability is fixed. No other official remediation or temporary workaround is documented. Patch status is not explicitly confirmed beyond the fixed version, so users should verify with vendor advisories for the latest guidance.
