Pywayne Data Structure

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only data-structure helper skill with expected examples for XML reading and writing, and no hidden execution or persistence behavior.

Use this skill if Chinese documentation is acceptable. When following the XmlIO examples, choose input and output paths carefully because writing XML may create or overwrite the destination file.

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

Most of the user-facing documentation is written in Chinese, and the file does not indicate that this language choice is optional or region-specific. The stated policy requires flagging language or locale constraints when the skill forces a specific language without user opt-in.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
91% confidence
Finding

This markdown file documents XmlIO read/write behavior, including writing to an output XML file, but it does not include any user warning about filesystem modification or potential overwrite effects. For markdown files, SQP-2 applies when descriptions omit warnings about behaviors that could affect user data or system integrity.
