Security audit

pdf-to-word

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward PDF-to-Word converter that reads a user-provided PDF and writes a DOCX output, with no evidence of hidden network, credential, persistence, or destructive behavior.

Install only if you are comfortable using a Chinese-language PDF conversion skill and the pdf2docx dependency. The skill will process the PDF files you provide and create DOCX output files; avoid giving it sensitive PDFs unless you trust the local environment and dependency chain.

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

Finding

The module docstring and all user-facing descriptions are written only in Chinese, indicating the skill is designed around a fixed language/locale. The file does not offer any user opt-in or language selection, and no region-specific justification is provided, which matches the policy's language/locale violation criteria.
