TikTok Shop Product Details by Gecho

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed TikTok Shop product lookup workflow that depends on Gecho's MCP server and Chrome extension, with some third-party setup and local-save cautions but no artifact-backed deception or unsafe automatic behavior.

Before installing, confirm you trust Gecho Bridge and its Chrome extension, because this workflow uses your logged-in browser session to access TikTok Shop data. Prefer a trusted save directory, review any raw files before sharing them, and consider pinning or reviewing the MCP package version instead of always using @latest if your environment requires stricter supply-chain control.

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
Vulnerability Patterns
  • System Prompt LeakageDirect Leakage, Indirect Extraction, Tool-Based Exfiltration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Confidence
98% confidence
Finding

The skill instructs users to install and run an MCP server via npx ... @latest, which fetches and executes the newest package version at runtime without pinning or integrity verification. If the upstream package is compromised or a breaking/malicious release is published, users could execute attacker-controlled code on their local machine during setup.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
84% confidence
Finding

The markdown states that the skill 'saves raw results when possible,' which can affect user data handling and local storage, but it does not explicitly warn users about the potential sensitivity of saved marketplace data or advise them to choose an appropriate location carefully. Because this is a markdown skill description, omitted disclosure about data-impacting behavior falls under missing user warnings.
