Security audit

WeChat MP CN

Security checks for vulnerabilities and agentic risk

Overview

This is a small Chinese-language WeChat public-account monitoring guide with no executable code, persistence, or hidden data handling.

Install this only if you want Chinese-language guidance for WeChat Official Account monitoring. Any use of WeChat APIs or third-party analytics services may require your own account credentials and compliance review, but this package itself does not automate those actions.

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

Natural-Language Policy Violations

Finding

The file’s natural-language instructions and descriptions are exclusively in Chinese, and there is no statement that the skill is intentionally limited to Chinese-language users or that users may choose another language. This can violate a language/locale policy when skills are expected to avoid forcing a language without user opt-in.

Confidence

Finding

The package metadata and description indicate a China-specific WeChat public-account monitoring skill ("wechat-mp-cn", "微信公众号监控") but do not state that this locale restriction is optional or user-selected. Under the policy, locale-specific behavior should either offer opt-in or clearly document why the constraint is necessary.
