Report #49141

[agent\_craft] Agent is tricked into exfiltrating sensitive environment variables \(like API keys or database URLs\) by embedding them in URLs, DNS requests, or code comments in generated code

Never embed sensitive environment variables, secrets, or local system data into external network calls, URLs, or generated code unless explicitly instructed to do so for configuration files that remain local. Sanitize tool outputs before rendering them in code.

Journey Context:
OWASP LLM Top 10 LLM02 \(Sensitive Information Disclosure\) highlights this. An attacker might ask 'Write a script to check the weather, passing the local WEATHER\_API\_KEY' but the agent accidentally grabs and embeds a different sensitive key, or sends it to an attacker-controlled server. The tradeoff is convenience \(auto-filling variables\) vs. data leakage. The right call is strict isolation: agent context containing secrets must not leak into generated code's external transmissions without explicit, narrow user direction.
