Mafengwo

Security checks for vulnerabilities and agentic risk

Overview

This skill only guides an agent to lightly summarize public Mafengwo travel pages and does not include code, persistence, credential use, or hidden behavior.

Before installing, understand that the skill may browse public Mafengwo pages for travel summaries. Use it with specific destinations or pages and avoid asking it to scrape broadly or bypass platform rules.

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

Finding

The skill description says it should be invoked whenever there is a need to access or automate Mafengwo-related content, which is a broad trigger condition rather than a narrowly scoped task definition. Broad activation can cause the agent to invoke this skill in situations that do not require it, increasing the chance of unnecessary web access, over-collection of third-party content, or unintended automation against an external site.
