Dollar General API - Store Prices, Stock, Deals, Coupons

Security checks for vulnerabilities and agentic risk

Overview

The skill provides disclosed shopping lookups through Scavio, with ordinary privacy, API-credit, and optional software-install considerations.

Scavio receives your searches and supplied location; prefer a ZIP over precise coordinates when sufficient. Protect your API key and account for per-request credit usage. If using MCP, limit enabled platforms to those needed. Optional SDK/MCP package code and the service's data-retention practices were not verified by this artifact review.

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

Output Handling
Confidence

Finding

The workflow instructs the agent to submit the user's ZIP code or latitude/longitude and product queries to Scavio's API. Although the service and endpoints are documented, there is no user-facing privacy notice explaining that location and shopping queries are transmitted to a third-party provider.
