Chenlang

Security checks for vulnerabilities and agentic risk

Overview

This is a plain Chinese-language informational skill about WeChat with no executable behavior or hidden authority.

Install this if you want Chinese-language reference material about WeChat. Non-Chinese-speaking users may find it less useful unless they are comfortable using translation, but no security-sensitive behavior was found.

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

Natural-Language Policy Violations

Medium

87% confidence
Finding
The description and all user-facing instructional content are presented exclusively in Chinese, which can amount to a language/locale policy violation when no user opt-in or alternative language option is provided. The file does not state that the skill is intentionally region-specific or limited to Chinese-speaking users.
