CVE-2026-34037

CRITICAL 9.9 PoC AVAILABLE

Published 2026-07-07 · Last modified 2026-07-07

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, the cloneTo() Livewire action in ResourceOperations.php authorizes the source resource but resolves destination resources with unscoped Eloquent lookups, allowing an authenticated user to clone resources into destinations owned by other teams and access cross-tenant resources. This issue is fixed in version 4.0.0-beta.464.
