TikTok Shop Product Search by Gecho

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent TikTok Shop product-search helper, but it depends on a third-party MCP server and Chrome extension that users should install deliberately.

Install this only if you are comfortable using Gecho's MCP server and Chrome extension with a logged-in TikTok Shop session. Prefer a pinned, reviewed Gecho Bridge version if available, and remove the MCP configuration or extension when you no longer need the workflow.

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

Confidence

Finding

The skill instructs users to launch an MCP server via npx ... @latest, which pulls and executes the newest published package at runtime without pinning an immutable version. If the upstream package is compromised, maliciously updated, or a dependency is hijacked, users could execute attacker-controlled code on their local machine during setup.
