Security
3 findings: 1 critical severity, 1 high severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
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 high-risk: it explicitly teaches how to locate and exploit file path traversal/LFI to read sensitive files (credentials, keys, config), exfiltrate data, and escalate to remote code execution.
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 extracting and reporting file contents (e.g., /etc/shadow, private SSH keys, wp-config.php) as "Exploitation Proof", which requires the LLM/agent to handle and output sensitive secret values verbatim.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
This skill explicitly instructs how to read sensitive system files (e.g., /etc/shadow, private SSH keys) and escalate LFI to RCE (log poisoning, php wrappers, expect://), which both disclose and enable modification/execution on the host—directly pushing an agent to compromise the machine state.
