Is this vulnerability remotely exploitable?

Yes, in typical web deployments it can be exploited remotely by any authenticated user who can reach the Frappe web UI or APIs that support document sharing.

What level of access does an attacker need to exploit this?

An attacker needs a valid user account with the ability to initiate share actions on at least some documents. They do not need administrative privileges; ordinary users may be able to leverage the flaw if sharing is available to them.

What is the safest general fix pattern for this issue?

Implement strict server-side checks in the sharing logic to ensure that users can grant only permissions they already hold on the specific document, and centralize these checks in a reusable authorization component to avoid inconsistent behavior.
