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 in coollabsio's Coolify product. Before version 4.0.0-beta.474, the PostgreSQL healthcheck command generation used attacker-controlled inputs (postgres_user and postgres_db) directly in shell commands without proper neutralization. This improper handling allows an authenticated user to inject and execute arbitrary OS commands within the database container environment. The vulnerability is addressed in version 4.0.0-beta.474.
Potential Impact
Successful exploitation allows an authenticated user to execute arbitrary OS commands in the database container, potentially leading to full compromise of the container environment, including confidentiality, integrity, and availability impacts as indicated by the CVSS score of 8.8 (high severity).
Mitigation Recommendations
Upgrade to version 4.0.0-beta.474 or later where this vulnerability is fixed. Patch status is not explicitly confirmed in the advisory, but the description states the issue is fixed in 4.0.0-beta.474. No additional vendor advisory content is provided. Until upgrade, restrict authenticated user privileges to minimize risk.
