ALDI Grocery Data API - Store Prices, Stock, Stores

Security checks for vulnerabilities and agentic risk

Overview

The skill provides clearly disclosed ALDI grocery lookups through Scavio, with ordinary privacy, API-key, and usage-cost considerations.

Scavio receives your ZIP code, selected store, and grocery searches, and requests consume credits. Keep your API key in an environment variable or secret store. If using MCP, enable only the platforms you need. External SDK/MCP implementations and Scavio's data-retention practices were not verified.

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 (4)

The workflow sends the user's ZIP code and grocery searches to Scavio without a user-facing privacy warning.

Finding

The workflow instructs the agent to submit the user's ZIP code and search terms to endpoints hosted by Scavio, a third-party intermediary. Although the API host and request parameters are documented, the skill does not instruct the agent to warn users that their location and shopping queries will be shared with that service.
