exploit-command-injection
OS Command Injection — exploiting applications that pass user input to OS commands without sanitization. Covers injection operators (;, |, ||, &&, $(), backticks, newline), blind detection (time-based, OOB callback), and bypass techniques (space, keyword, encoding).

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 an explicit offensive guide for exploiting OS command injection and performing remote code execution and data exfiltration (including credential theft and OOB callbacks), indicating deliberate malicious intent.
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
This skill explicitly instructs the agent to locate and exfiltrate sensitive files (e.g., cat /.env, /etc/shadow) and to send their contents via HTTP/DNS/time-based oracles, which requires the LLM/agent to handle and output secret values verbatim.
