GoBuy the Trust Layer for Agentic Commerce

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed shopping-trust helper that uses GoBuy services to score products, reviews, and stores, with no local code execution or hidden persistence found.

Before installing, consider that using the skill may query GoBuy-hosted services with product, retailer, or store identifiers, and treat its scores as evidence signals rather than guarantees about product quality, safety, or legitimacy.

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

Finding

The trigger description is very broad, covering multiple retailers, review-authenticity questions, generic trust/buy queries, alternatives, and store safety checks. This can cause the skill to activate in contexts the user did not explicitly intend, leading to unnecessary external lookups, incorrect tool routing, or overreach into purchase-related decisions based on loosely matched prompts.
