Is this vulnerability remotely exploitable?

Yes, if an attacker can reach the Budibase file upload endpoints over the network, they can bypass UI restrictions using crafted HTTP requests. Exploitability depends on how the Budibase instance is exposed (internal-only vs. internet-exposed).

What level of access does an attacker need?

Typically, the attacker needs at least the same level of access as any user permitted to upload files through the application. In many internal-tool scenarios, this may be a standard authenticated user, but the exact requirement is deployment-specific.

What is the safest general fix pattern?

Implement robust, server-side file validation and handling: enforce strict allowlists on the backend, store uploads in non-executable locations, and ensure that uploaded content is not interpreted as active code by default.
