HIGHData Exfiltrationconfidence: 0.7

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

MEDIUMExcessive Agencyconfidence: 0.75

Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.

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.
