Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Foxit PDF-to-Word automation guide, with ordinary file-conversion risks but no evidence of hidden or malicious behavior.

Install only if you use Windows with the Chinese Foxit UI and are comfortable with GUI automation. Before batch conversion, choose an output folder carefully and back up or rename any existing .docx files that might share the same output names. Also note that the inspected package does not include the referenced PowerShell script, so it may be incomplete as published.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The documentation states that the system language must be Chinese because the menu shortcut mapping is based on the Chinese version. This is a language/locale constraint presented as mandatory, with no user choice or explicit justification that the skill is intended only for a China-specific environment.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill explicitly pastes a full output path into Foxit's save field and states this is done to avoid the 'file already exists' prompt, but it does not clearly warn users that an existing .docx at that path may be replaced. In a file-conversion workflow, silent overwrite behavior can cause unintended data loss, especially during batch runs or when output names are customized.
