How widely exploitable is this vulnerability?

This vulnerability can be exploited wherever an Appsmith instance exposes public apps and uses the affected endpoint without strict authorization for edit‑mode actions. Any unauthenticated user with network access to such an instance may attempt to execute unpublished actions if the publish boundary is not enforced server‑side.

What level of access does an attacker need?

The attacker typically needs only network access to the Appsmith deployment and the ability to interact with a publicly accessible app. No login or editor privileges are required, because the flaw occurs when the backend implicitly trusts client-controlled execution mode parameters.

What is the safest general fix pattern?

The most robust fix is to enforce authorization centrally for action execution, deriving execution mode exclusively from the authenticated user's role and the app's published state. Public, unauthenticated users should be hard‑restricted to published actions, with all edit‑mode functionality residing behind authenticated, role‑aware endpoints.
