file-path-traversal
This skill should be used when the user asks to "test for directory traversal", "exploit path traversal vulnerabilities", "read arbitrary files through web applications", "find LFI vulnerabilities", or "access files outside web root". It provides comprehensive file path traversal attack and testing methodologies.

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 provides explicit, actionable instructions to exploit file path traversal vulnerabilities for reading sensitive files, stealing credentials/keys, and achieving remote code execution (log poisoning, php wrappers), indicating high malicious intent and clear abuse potential.
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 directs extracting and reporting file contents (e.g., /etc/shadow, SSH private keys, /proc/self/environ) as "Exploitation Proof", which requires the LLM to handle and output 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 gives explicit payloads and step-by-step instructions to read sensitive system files (e.g. /etc/shadow, SSH private keys), perform log poisoning and escalate LFI to RCE, which directly enable compromising or modifying system files and thus can be used to compromise the machine the agent runs on.
