CVE-2026-57498
CRITICAL 9.6 PoC AVAILABLECoolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.474, Coolify's API controllers consistently validate server ownership with Server::whereTeamId($teamId) before any operation. However, multiple Livewire web UI components accept server_id and destination_uuid from URL query parameters without any team ownership validation, allowing cross-team resource deployment. This vulnerability is fixed in 4.0.0-beta.474.
Public exploit or PoC code exists. Modeled probability is still low, but the barrier to attack is reduced — watch closely.
