HIGHData Exfiltrationconfidence: 0.7

Code accesses environment variables that may contain secrets (API keys, tokens). This is a common pattern for credential theft.

HIGHOutput Handlingconfidence: 0.95

Model output is used without validation or sanitization. Unvalidated output injected into downstream contexts (SQL, shell, HTML) enables injection attacks and arbitrary code execution.
