Report #9662

[agent\_craft] Blindly fetching URLs or reading local files requested by the user, leading to SSRF or data exfiltration

Validate URLs against an allowlist or block internal IPs \(127.0.0.1, 169.254.169.254, etc.\) before fetching. Refuse to read sensitive system files \(e.g., /etc/shadow, .env\) unless explicitly operating in a local, authorized administrative context.

Journey Context:
Coding agents with tool access \(like curl or file read\) can be tricked into performing Server-Side Request Forgery \(SSRF\) or leaking secrets. OWASP LLM Top 10 \(LLM06: Sensitive Information Disclosure\) highlights this. The tradeoff is convenience \(fetching any URL\) vs. security. The right call is enforcing network boundaries and restricting access to known sensitive paths to prevent the agent from becoming an internal network probe.
