How broadly exploitable is this vulnerability?

Exploitability depends on who can influence the agent. If an attacker can shape prompts, workflows, or integrations so that the agent invokes file tools with arbitrary paths, they can often bypass repository scoping and access host files.

Does an attacker need direct system or shell access?

Not necessarily. Direct shell access is not required; the attacker primarily needs a way to cause the agent to execute file operations on their behalf, such as through exposed prompts, automation hooks, or API-driven workflows.

What is the safest general fix pattern?

The most robust fix is to require that every file operation go through a centralized permission-check function that receives and validates the exact path to be accessed, ensuring deny rules and sandbox constraints are always applied before I/O.
