Security audit

Security checks for vulnerabilities and agentic risk

Overview

This is a local Chinese-language teacher communication assistant that stores teacher and student communication notes only with user confirmation and does not show hidden upload, remote execution, or deceptive behavior.

Install this only if you want a Chinese-language assistant that keeps local teacher and student communication archives. Because it may store sensitive student-related summaries, choose an appropriate local archive location, review previews carefully, and avoid entering unnecessary identifiers such as addresses, phone numbers, or ID numbers.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
91% confidence
Finding

The skill instructs the agent to read and write teacher and student profile files and to execute a local management script, but it does not declare any explicit tool scope or allowed-tools boundary. That mismatch increases the risk of overbroad file access or unintended writes, especially because the skill handles sensitive education records and temporary payload files.

Finding

文件标题、名称和操作说明均默认并强制在中文语境下执行,但未说明这是仅面向中文教师用户的区域化技能,也未给出语言选择或用户确认。这可能构成语言/区域策略上的自然语言约束问题。

Finding

L003 的描述使用了“需要准备家长沟通”“处理家长质疑”“准备电话面谈”等宽泛条件,覆盖面很大,但没有明确边界、排除条件或更具体的触发短语。这类表述容易匹配大量普通教学沟通场景,增加非预期调用的风险。

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

This markdown guidance forces a specific language/locale in the skill content and does not indicate that users may opt into another language. Under the policy, language constraints should either be optional or clearly justified as region-specific.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

This file contains natural-language instructions exclusively in Chinese, including normative requirements for how profile fields and records should be structured. There is no indication that users may choose another language or that the Chinese-only constraint is an explicitly justified regional requirement, which matches the language/locale policy concern.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The file’s instructional content is entirely in Chinese and does not indicate that language selection is optional or that the skill is intentionally limited to a Chinese-speaking context. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation.

Scope Creep

Low
Category
Excessive Agency
Confidence
70% confidence
Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.

Finding

This code file contains natural-language strings that define the tool’s behavior and user interface in a single language only. Under the policy, forcing a specific language without offering a language or locale choice is a natural-language policy violation.
