Kroger Grocery Data API - Search, Product Detail, Multi-Banner

Security checks for vulnerabilities and agentic risk

Overview

The skill provides grocery product lookups through a clearly disclosed third-party API, with no evidence of hidden access or harmful actions.

Scavio receives your lookup inputs and charges credits per request. Keep its API key in an environment variable or secret store. If using the optional MCP setup, limit enabled platforms to those you need; its example includes default platforms alongside Kroger.

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
