Is this vulnerability remotely exploitable over the internet?

It can be exploited remotely, but only by authenticated users who have Global Builder privileges and can reach the `/api/plugin/upload` endpoint; it is not exploitable by anonymous users under normal configurations.

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

An attacker must have valid credentials and Global Builder permissions in the Budibase instance, giving them the ability to upload plugins.

What is the safest general fix pattern for developers?

The robust fix is to ensure all filesystem operations use server-generated paths, validate and canonicalize any path components derived from user input, and enforce that the final resolved path stays under a known-safe upload directory before performing deletes or writes.
