Nordstrom Product Data API - Search, Reviews, SKU Stock, Store Pickup

Security checks for vulnerabilities and agentic risk

Overview

ClawScan rates this skill benign with medium confidence: the reported API calls appear aligned with Nordstrom product lookups, though the scan was partial and flagged a missing notice about sharing location data.

Consider whether you are comfortable sending product queries and, for store searches, your ZIP code to Scavio. ClawScan’s verdict is benign, but confidence is medium and the scan was partial: it reported unresolved local references, so the evidence is incomplete.

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
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Finding

L087 instructs the agent to call /nordstrom/stores with the user's ZIP code, and L718 repeats this instruction. Requests go to the third-party service at api.scavio.dev, but the skill does not warn the user that their location will be shared with Scavio rather than only with Nordstrom.
