Security audit

Lowe's Product Data API - Store Price, Stock, Search, Reviews

Security checks for vulnerabilities and agentic risk

Overview

The skill provides Lowe’s product lookups through Scavio, with expected sharing of search details and ZIP codes.

Scavio receives your ZIP code, searches and requested product identifiers, and requests consume credits. Protect your API key. Prefer direct API calls or restrict optional MCP tools to those you need. This assessment covers the supplied instructions; external packages and the live service were not audited.

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 workflow instructs the agent to submit the user's ZIP code and product search terms to Scavio, a third-party service. Although the skill documents the API provider and endpoints, it does not warn users that their location-related data and queries will be shared with that provider.
