Security audit

Pdf Batch Tool

Security checks for vulnerabilities and agentic risk

Overview

This PDF utility skill is coherent and limited to user-directed PDF file operations, with no hidden code or persistence found.

Before installing, confirm you are comfortable using Chinese instructions and choose output paths carefully because the examples create files and directories that could overwrite existing work if reused.

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
94% confidence
Finding

All invocation examples and headings are presented in Chinese, and the feature list explicitly highlights Chinese support, but the document does not indicate whether other languages are supported or that Chinese is a required locale. This can violate language-choice policy when a skill effectively forces one language without user opt-in or justification.

Missing User Warnings

Confidence
85% confidence
Finding

This markdown file documents operations that create new files and directories, such as merged PDFs, extracted text, images, and compressed outputs. It does not include any warning about potential overwrites, disk usage, or the need to verify output paths before running, which is a user-facing safety disclosure expected for data-affecting file operations.
