How widely exploitable is this vulnerability?

Exploitation is constrained to users who already have low-privileged member access and can obtain an administrator's invitation link. However, in environments where invitation URLs are easily exposed (for example, shared channels or logs), the practical risk can be high because a member can turn that access into full administrative control.

Does an attacker need prior authentication to exploit this issue?

Yes, the described scenario assumes the attacker is a low-privileged member within the same Coolify instance. They must be able to see and reuse an invitation link that was intended for an administrator and redeem it before the legitimate recipient.

What is the safest general fix pattern for developers?

The most robust pattern is to bind each invitation to a specific, pre-verified identity and enforce strict checks at redemption time, ensuring that only the intended recipient can use the invitation. Additionally, invitations should be single-use, short-lived, and should not directly grant administrative roles without additional verification or approval.
