CVE-2026-42200 Details
Description
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.
A path traversal vulnerability has been identified in Coolify versions prior to 4.0.0-beta.474. The issue arises in the PostgreSQL initialization script handling, where user-controlled filenames are not properly validated, allowing authenticated users to write files outside the intended directory. This vulnerability can be exploited to inject a malicious cron job that executes commands with root privileges, leading to remote code execution on the server.
Users are advised to update to Coolify version 4.0.0-beta.474 or later, where this vulnerability has been patched.
