2 findings: 1 critical severity, 1 high 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 explicitly instructs performing remote code execution via HTTP query parameters to read target files and harvest flags/credentials (including /etc/passwd, .env, SSH keys), i.e. intentional data exfiltration and RCE/backdoor behavior.
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 the agent to re-echo discovered flags VERBATIM in its next response (e.g., "Flag captured: FLAG{...}"), which requires the LLM to handle and output secret values directly, creating an exfiltration risk.
