Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward Chinese-language PPT creation and design helper with no executable code, persistence, credential handling, or hidden system access.

Install this if you want a Chinese-language assistant for making or improving presentations. Review any private source documents before providing them to the agent, since the skill is designed to read user-supplied materials and summarize them into slides.

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

Finding

Mixing characters from multiple Unicode scripts in a single identifier is a common technique to create visually ambiguous tool names.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill name and full description are written exclusively in Chinese, and the instructions throughout the file direct behavior in Chinese without indicating that the user can choose another language. This creates a natural-language locale policy concern because it implicitly fixes the interaction language rather than offering opt-in or flexibility.
