Is this vulnerability remotely exploitable over the internet?

Yes, if a Budibase instance is exposed and an attacker can obtain access to a workspace or account that permits creating or editing REST datasources. In that case, they can supply arbitrary target URLs and leverage the server to reach internal resources.

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

Typically, an attacker needs at least authenticated access that allows them to define or modify REST datasource connectors, or the ability to influence those URLs indirectly. The exact access level depends on how roles and workspaces are configured in the particular deployment.

What is the safest general fix pattern for this type of bug?

The safest pattern is to design outbound network access with a
