Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrowly scoped Chinese teacher assistant for drafting student progress and renewal reports, with clear limits on student data use and no evidence of hidden execution or message sending.

Before installing, users should be comfortable with the skill reading one named student's learning records, homework follow-ups, course-package status, and consent fields to draft reports. Parent-facing content should only be generated when the consent fields allow it, and teachers remain responsible for manually sending any report or renewal message.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Medium
Confidence
91% confidence
Finding
The note text is written as an instruction in Chinese and the schema descriptions throughout the file are also Chinese-only, with no indication that users or operators can choose another language or that the skill is intentionally limited to a Chinese-language context. Under the policy, forcing a specific language without opt-in or clear justification is a natural-language policy concern.
