Is this vulnerability remotely exploitable over the internet?

Yes, if the Budibase deployment exposes the affected webhook endpoint to the internet or any untrusted network, an attacker can exploit it remotely without authentication.

Does an attacker need any credentials or prior access to exploit this?

No. The vulnerability can be triggered by any party that can reach the public webhook URL associated with an automation containing a Bash step.

What is the safest general fix pattern for this kind of issue?

The safest pattern is to remove or strictly limit raw shell execution in automations, enforce authentication/authorization on all externally reachable webhooks, and run automation workers with minimal privileges rather than as root.
