WeChat MiniProgram Dev

Security checks for vulnerabilities and agentic risk

Overview

This is a Chinese-language WeChat Mini Program reference skill with documentation examples, not a skill that runs code or sends user data.

This skill is appropriate if you want Chinese-language help with WeChat Mini Program development. Treat the included API endpoints, storage calls, and privacy-related examples as templates to adapt carefully in your own project, especially before adding real network domains, user data handling, or sensitive Mini Program permissions.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding

The manifest description and top-level heading present the skill entirely in Chinese and frame it as the default interaction mode, without indicating that other languages are supported or that the user can choose their preferred language. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation.

Confidence

Finding

The entire document is written in Chinese and does not indicate that language choice is optional or user-selectable. Per the policy criteria, natural-language content that effectively forces a specific language without opt-in is a locale/language policy concern.
