Nordstrom Rack Product Data API - Clearance, Flash Events, Store Pickup, Reviews

Security checks for vulnerabilities and agentic risk

Overview

ClawScan’s verdict is benign with medium confidence: the reported Scavio API calls fit the product-data skill’s purpose, while the scanner notes a missing privacy notice for location lookups and incomplete reference resolution.

The verdict is benign, but consider whether you are comfortable sending product queries and possibly your ZIP code or coordinates to Scavio. Skillspector’s scan was partial because it could not resolve some local path-like references, so the evidence is incomplete.

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

Findings (11)

The store-lookup workflow sends the user's location to Scavio without a privacy warning.

Finding

The workflow instructs the agent to call the stores endpoint with the user's ZIP code, and the guardrails repeat this instruction at L734. Although the document identifies Scavio's API and supports ZIP codes or precise coordinates, it never warns the user that their location will be transmitted to a third-party service rather than used locally or sent only to Nordstrom Rack.
