Report #4323

[agent\_craft] Agent is tricked into exfiltrating local files by making a tool call \(like 'curl'\) with the file contents in the URL parameters

Sanitize tool call arguments. Block outbound requests to non-allowlisted domains or those containing suspiciously large payloads/known file paths.

Journey Context:
Indirect prompt injection can command an agent to 'phone home.' Since the agent has file access, it can read secrets and send them out. The agent loop must inspect tool calls for data leakage vectors before execution, treating outbound network calls as high-risk actions.
