CVE-2026-42200: Coollabsio Coolify

High severity, CVSS 8.8. EPSS: 0.9% chance of exploitation in the next 30 days.

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.474, PostgreSQL initialization script (generate_init_scripts() method in app/Actions/Database/StartPostgresql.php) filename handling did not sufficiently restrict paths, allowing an authenticated user to write files outside the intended directory and achieve command execution through database initialization. This issue is fixed in version 4.0.0-beta.474.

Affected products

• Coollabsio Coolify: before 4.0.0-beta.474 (fixed in 4.0.0-beta.474)
