How broadly exploitable is this vulnerability?

Exploitation is limited to environments where an attacker can obtain or create a low-privileged member account on the affected Coolify instance. Within such environments, the issue can reliably lead to administrator-level compromise using only the web interface.

Does an attacker need direct server or database access to exploit this?

No. The vulnerability is exploitable through normal application workflows in the Coolify UI or corresponding HTTP endpoints. Only valid member-level credentials and access to the invitation functionality are required.

What is the safest general fix pattern for developers?

The safest fix is to enforce centralized, server-side authorization checks on every operation that creates, invites, or modifies high-privilege accounts, and to ensure that no code path for invitations can bypass these checks. Any role escalation or admin creation should be strictly restricted to existing admins and validated in the backend.
