Is this vulnerability remotely exploitable?

Yes, in the sense that an attacker does not need direct access to the victim's shell. If they can control or influence text that the model reads—such as repository content, documentation, or shared prompts—they may cause HAI Build Code Generator to generate and auto-execute malicious commands.

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

The attacker needs the ability to inject content into a channel the model consumes (for example, a pull request, ticket, README, or shared prompt). They do not need local code execution initially; the vulnerable auto-execution feature grants that when it trusts the model's "safe" classification.

What is the safest general fix pattern?

Decouple security from the model by: - Removing or severely restricting auto-execution, - Requiring explicit, informed user consent for impactful commands, and - Enforcing a strict, code-level allowlist of what can be run automatically, independent of model judgment.
