Cn Smart Email

Security checks for vulnerabilities and agentic risk

Overview

This is a simple local Chinese email classification and reply-template helper with no hidden access, persistence, or network behavior found.

Install this only if you want a local Chinese-language helper for simple email classification and canned replies. Do not treat it as a full email client or multilingual assistant; it does not connect to mail accounts, send messages, or understand sensitive context beyond the text you paste into it.

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

Findings (2)

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The module docstring names the skill as a Chinese email classification and reply assistant, and all user-facing strings and reply templates are fixed in Chinese. This indicates a language constraint without any opt-in, fallback, or documented region-specific justification, which fits the language/locale policy violation category.

Natural-Language Policy Violations

Low
Confidence
91% confidence
Finding
The markdown explicitly states support for Chinese email scenarios, and the skill name and surrounding documentation are entirely Chinese-language without indicating that users can choose another language or locale. This can be a language/locale policy concern because it implicitly constrains usage to Chinese without documented opt-in or alternatives.
