Security audit

Study Plan

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple study-plan helper with minor documentation and language limitations, not a security threat.

Install this if you want a mostly Chinese-language study planner. Be aware that one helper script stores local task entries in a study-plan data folder and that some task-management commands appear incomplete or demo-like rather than fully functional.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The description says "Use when you need study plan capabilities. Triggers on:." but does not provide any actual trigger phrases or constraints. This leaves activation scope unclear and could cause unintended invocation because there are no specific trigger examples or exclusion conditions.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The help text advertises state-changing task-management commands such as 'done', 'priority', 'remind', and 'clear', implying they affect the underlying study plan data. However, the corresponding implementations at L047-L080 only echo status text and append to history.log, while leaving the main data file unchanged, which contradicts the documented behavior of those commands.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

This shell/Python skill presents its title, help text, commands, and generated content entirely in Chinese, indicating a fixed language experience. The file does not offer a language choice or explain that it is intentionally limited to a Chinese-speaking or region-specific context, which matches the locale-policy violation criteria.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
74% confidence
Finding

The natural-language description mixes Chinese and English, but there is no statement that the skill will adapt to the user's preferred language or ask for language choice. This can create a language/locale policy concern if the skill defaults to a language without explicit user opt-in.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
86% confidence
Finding

In the help text, 'export' suggests a dedicated export capability, typically implying conversion or writing data to an export target. The implementation at L082-L085 merely cats the existing data file to standard output, which is materially different from the documented intent of an export command.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
92% confidence
Finding

The file's substantive guidance is written in Chinese, which imposes a specific language on users without any stated opt-in or alternative locale option. Under the policy, forcing a specific language without user choice is a natural-language policy concern.
