Is this vulnerability remotely exploitable?

Yes, but only by authenticated users who can create or modify workflows and then trigger them. There is no unauthenticated remote exploit described; the attack originates through the n8n interface or API.

What level of access does an attacker need?

The attacker must have a user account on the n8n instance with permissions to design or edit workflows and to run those workflows. Without workflow authoring capabilities, the described attack chain is not possible.

What is the safest general fix pattern?

The safest pattern is to ensure that workflow-exposed features cannot generate or modify files that are later interpreted in an executable context, especially by tools like git. This includes constraining file write locations, sanitizing and validating any data that may influence commands, and decoupling user-controlled workflow steps from host-level tooling.
