Is this vulnerability remotely exploitable or does it require local access?

It primarily targets local developer environments, but it is exploitable remotely in the sense that an attacker can publish or distribute a malicious repository. When a developer clones and opens that repository in VS Code with a vulnerable Ruby LSP installed, arbitrary code execution can occur.

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

An attacker needs the ability to influence the code workspace a developer opens, typically by providing a repository or project folder containing a crafted `.vscode/settings.json`. They do not need direct access to the developer's machine or VS Code.

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

The safest pattern is to stop treating configuration values as code. Restrict configuration fields to well-validated, non-executable values (e.g., simple strings from a whitelist) and avoid interpolating them into files that will be executed by interpreters or build tools.
