Report #27664

[agent\_craft] Agent tricked into exfiltrating sensitive repository data via malicious tool calls or external API requests

Implement strict allow-lists for external domains the agent can contact. Never send repository contents, environment variables, or local files to untrusted or user-specified endpoints. Validate all outbound tool calls against a safety policy before execution.

Journey Context:
OWASP LLM06 \(Sensitive Information Disclosure\) and LLM02 \(Insecure Output Handling\) highlight risks where agents leak data. A common jailbreak involves asking the agent to post codebase secrets to a webhook. The agent must treat outbound network calls as high-risk actions requiring explicit, strict validation, preventing the codebase from becoming a data exfiltration vector.
