How broadly exploitable is this vulnerability?

Any authenticated Creator-level user in an affected Budibase instance can exploit this issue, provided they can send custom HTTP requests to the backend API. The vulnerability does not require prior administrative access, but it is limited to users who already have Creator permissions.

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

No. Exploitation only requires application-level access: an authenticated Creator account and network reachability to the Budibase HTTP API. The attack can be carried out using standard tools (e.g., browser dev tools or API clients) to modify or replay invitation requests.

What is the safest general fix pattern for developers?

Consolidate user management logic behind server-side authorization controls that strictly check the acting user's role before allowing invitations, role assignments, or group changes. Never rely solely on UI restrictions, and ensure that all administrative actions are enforced by centralized permission checks in the backend.
