High

W007: Insecure credential handling detected in skill instructions

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

Insecure credential handling detected (high risk: 0.80). The skill requires producing decoded Base64 payloads and raw IOCs in its JSON report, which could include verbatim credentials or tokens extracted from event logs, so the LLM may output sensitive secret values if present.
