CVE-2026-42200
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.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
