Security audit

Google Maps API

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward guide for using a paid Google Maps-style API service, with its network, payment, and credential use disclosed.

Before installing, confirm you trust fetcher.sh with your search queries and any location coordinates, understand the $0.005-per-call pricing and no-refund note, and protect the FETCHER_API_KEY like any paid service credential.

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
