Security audit

Micro Center API - Store Stock, Open Box, Prices

Security checks for vulnerabilities and agentic risk

Overview

The skill’s disclosed API access fits its purpose of checking Micro Center products, prices, and stock.

Scavio receives your search terms and store selections, and requests consume credits. Keep the API key private and restrict the optional MCP integration to needed tools. The scanner’s reference gaps were resolved through artifact inspection; external SDK/MCP code and service-side handling remain outside this review.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • 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
