Pipeworx wikiviews

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small Wikipedia pageview lookup helper that uses a disclosed external MCP endpoint and does not show hidden execution, persistence, credential use, or local data access.

Before installing, be aware that Wikipedia pageview queries will be sent to the disclosed Pipeworx gateway rather than directly to Wikimedia, so avoid sending sensitive private research topics if that matters to you.

A.I.G

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
