Report #39843

[agent\_craft] Leaking sensitive environment data via tool calls \(e.g., webhooks, external API requests\)

Validate all outbound network tool calls \(e.g., fetch, curl, HTTP requests\). Block or prompt for user confirmation if the destination URL is untrusted or if the payload contains environment variables, secrets, or user PII. Never pass raw secrets into external tool call arguments.

Journey Context:
A common jailbreak vector is tricking the agent into reading a secret \(like a GitHub token\) and sending it to an attacker-controlled server via a webhook tool call. OWASP LLM Top 10 LLM06 \(Sensitive Information Disclosure\) highlights this. Agents must treat outbound data flows with the same scrutiny as inbound data, preventing the tool execution layer from becoming a data exfiltration channel.
