E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
This document is a deliberate, actionable exploit guide showing step-by-step techniques to upload webshells, achieve remote code execution, and exfiltrate sensitive files/credentials.
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
The skill explicitly instructs fetching and printing sensitive files/variables (e.g., curl ...?cmd=cat+/.env and printenv|grep ...) which requires the LLM/agent to receive and output secret values verbatim, creating an exfiltration risk.
