Is this vulnerability remotely exploitable?

It can be influenced remotely through prompt injection or malicious instructions provided to the AI, but actual exploitation occurs on the developer's machine or environment where Git is run. The attacker typically needs a way to control or influence what the AI writes into the repository.

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

The attacker needs the ability to drive the AI into writing or modifying files under `.git/`, which can happen via crafted prompts, injected content in code or documentation, or other untrusted project inputs that the AI is instructed to follow.

What is the safest general fix pattern for developers and tool builders?

Enforce strict authorization around sensitive repository control files: block or tightly gate writes to `.git` directories and hook scripts from AI or other untrusted components, and ensure that any automatically executed scripts originate only from trusted, reviewed sources.
