Security audit

Security checks across malware telemetry and agentic risk

Overview

This skill is a coherent WPS Office document helper whose file reads, file writes, and LibreOffice-based conversion are disclosed and tied to user-requested document work.

Install this if you want local WPS/Office document automation. Expect it to read and write the document files you point it at, create output files or backups, and use LibreOffice headless for conversions when available; review converted files for formatting drift before final delivery.

MCP Least Privilege
Confidence
92% confidence
Finding
The skill advertises and operationally relies on file read/write and shell-capable scripts, but does not declare corresponding permissions or capability boundaries. This creates a trust and enforcement gap: a caller or reviewer may assume the skill is low-risk documentation guidance while it can actually invoke local tooling and modify files, increasing the chance of unintended file changes or command execution.

Tp4

High
Category
MCP Tool Poisoning
Confidence
87% confidence
Finding
The skill description promises broad WPS-specific workflow support, but the described implementation actually routes key functions through auxiliary scripts and LibreOffice headless, with narrower behavior than advertised. This mismatch is dangerous because users may trust the skill for WPS-native or collaboration-sensitive tasks while the actual tooling may alter formatting, omit expected safeguards, or behave differently from WPS, leading to data integrity and workflow risks.
