Is this vulnerability remotely exploitable?

Yes. As described, a remote attacker who can reach the template creation functionality and provide crafted template content may be able to trigger arbitrary code execution on the server.

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

The attacker must be able to create or modify templates. In many CMS deployments, this requires at least some level of authenticated access, but misconfigurations or overly broad permissions can lower that bar.

What is the safest general fix pattern for this vulnerability?

The safest pattern is to ensure that template content is never treated as raw executable code. Use a template engine configured in a safe, non-Turing-complete mode, remove support for arbitrary code execution from templates, and strictly validate template syntax against an allowed subset.
