Report #62329

[agent\_craft] Agent tricked into exfiltrating sensitive environment variables via tool calls \(e.g., curl to attacker server\)

Sanitize and validate URLs/domains in tool arguments. Block outbound requests to private IP ranges \(SSRF prevention\) and prevent reading sensitive env vars \(like API keys\) into tool payloads without explicit user confirmation.

Journey Context:
Tool use gives agents immense power but creates a direct exfiltration channel. An attacker can inject a URL in a file, the agent reads it, and executes it via a tool. The agent must treat tool execution as a high-risk action requiring data flow validation and SSRF mitigations.
