Is this vulnerability remotely exploitable?

Yes, but indirectly. An attacker must first obtain an authenticated account with permissions to create or modify workflows using the Git node. From there, they can craft a workflow that, when executed, triggers arbitrary command execution or file reads on the host.

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

The attacker needs valid credentials to the n8n instance and sufficient permissions to design or modify workflows that include the Git node. No direct shell or host access is required; the workflow engine acts as the execution vehicle.

What is the safest general fix pattern for developers?

Replace shell-based Git invocations with library-level APIs or parameterized process execution functions that do not invoke a shell, and enforce strict validation and allowlisting of all workflow-controlled inputs that reach OS-level operations.
