Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Chinese education-advice persona skill with no bundled executable code, but its guidance is intentionally sharp and opinionated.

Install this only if you want a Chinese, Zhang Xuefeng-style education and career-advice persona. Treat its advice as opinionated commentary, verify current admissions and employment facts independently, and do not rely on it as the sole basis for major, school, or career decisions.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium

Confidence

Finding

The trigger conditions are broad enough to activate on generic education, major-selection, or planning questions without a clear opt-in to this specific persona. That can cause unintended routing, leading users to receive a highly opinionated, abrasive style when they did not request it, which increases the chance of misleading, low-context, or culturally mismatched guidance.

Natural-Language Policy Violations

Medium
Category

Confidence
87% confidence
Finding

The skill mandates a specific Chinese persona and response style without checking the user's language, region, or preference. This can override user expectations and produce advice in an unwanted language or culturally specific framing, reducing usability and potentially causing misunderstanding in sensitive education and career decisions.

Finding

This markdown file is entirely written in Chinese and presents content in a single language without offering any language or locale choice. Under the stated policy, forcing a specific language without user opt-in can be a natural-language policy violation unless the locale constraint is clearly documented and justified, which is not present here.
