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.
